While I’ve always loved holidays, now that I’m a mom, I totally feel that need to make those fun holiday memories and add a little magic to the day. With Halloween around the corner, I’m planning on making some Halloween Cupcakes for dessert, but I also came up with this monster breakfast sandwich recipe for our morning meal—and I thought I would share it with you too! Truth be told, these turned out so delicious, I’ll probably be making them year-round now. (With or without the monster face!)

Why These Monster Breakfast Sandwiches Belong on Your Halloween Menu

This recipe is so much fun, but it’s not just about the spooky look. They taste SO good too! Here’s why you’ll love them.

  • Easy to make. This is a recipe that’s not complicated to make, and it’s also easy because you can make the tofu scramble in advance and have it ready to go in the morning.
  • Packed with flavour. Between the savoury scramble, the buttery croissants, the fresh veggies, and the rich, creamy avocado mash, there’s so much deliciousness going on here.
  • Not just for breakfast. Even though they’re filled with a tofu scramble, there’s really no reason you can’t serve these for lunch or dinner! And you can also scale up the recipe for a cute party option.

Notes on Ingredients

Here’s what you’ll need to make this monster breakfast sandwich recipe. Scroll down to the recipe card to find the ingredient quantities and recipe instructions.

  • Croissants – I used croissants because they had the shape I wanted for these sandwiches, but I know vegan croissants aren’t always easy to find. Wildgrain (a mail order bakery) makes awesome vegan croissants, and many allergy-friendly bakeries have them too.
  • Tofu scramble – I use my Fluffy Tofu Scramble, but this Southwestern Tofu Scramble would also work.
  • Red bell pepper – This forms the monster’s tongue.
  • Avocado
  • Lime juice – Use freshly-squeezed lime juice.
  • Salt and pepper
  • Baby spinach
  • Cherry tomatoes – Grape tomatoes will also work, or use Roma tomatoes cut into slices.
  • Green olives with pimiento – For the eyes!
  • Toothpicks – These hold the eyes in place.

How to Make a Monster Breakfast Sandwich

Follow along with this step-by-step guide to see the process of making these monster sandwiches!

  • Make the avocado slime. Mash the avocado with lime juice, salt, and pepper.
  • Make the red pepper tongues. Cook the red pepper strips with oil in a skillet set over medium heat, just until softened.
  • Prep the eyes. Skewer the olives with toothpicks.
  • Assemble. Slice the croissants and spread the avocado on the bottom half. Add the tofu scramble, spinach, and tomatoes, followed by the red pepper to form the tongue. Close the croissant, then add the olive eyes.

Variation Ideas

Here are a few more ways you can make this monster breakfast sandwich recipe!

  • Take a shortcut. If you want to shave some time off of this recipe, you can use store-bought guacamole for the slime and skip cooking the red pepper tongues.
  • Swap out the croissants. You can use your imagination to create a different kind of monster by using pitas, hoagie rolls, or bagels. (I love these Gluten-Free Bagels, which are also vegan!)
  • Add vegan bacon. Slices of vegan bacon (like my Crispy Vegan Bacon) would be delicious layered into the sandwich, or you can use them to form the monster tongue instead of red bell pepper!

Serving Suggestions

Pair these monster breakfast sandwiches with Rainbow Fruit Salad for a wholesome side. For something a little more spooky and festive, buy a can of lychees and stuff the holes with blueberries for fruity eyeballs!

Make Ahead Tips

If you want to make these breakfast sandwiches ahead of time, rather than assembling them in advance, I recommend preparing each component the night before and refrigerating them separately.

  • Make the avocado mash, transfer it to an airtight container, and press plastic wrap directly onto the top to slow oxidation before adding the lid.
  • Cook the red pepper tongues and place those in an airtight container.
  • Make the tofu scramble and refrigerate that in an airtight container too.
  • Slice the cherry tomatoes and skewer the olives. Place those in another container.

When you’re ready to serve, just heat up the tofu scramble (or add it to the sandwiches cold or at room temperature; it doesn’t need to be heated) and assemble.

No ratings yet

Ingredients

  • 4 large croissants, 240g
  • 1 batch tofu scramble, about 2 cups / 480mL
  • 1 red bell pepper, sliced into long curved strips – 1 cup / 120g
  • 1 large ripe avocado, mashed – about ¾ cup / 180g
  • Juice of ½ lime, 15 mL
  • Salt and pepper, to taste
  • 1 cup baby spinach, 30g
  • 1 cup cherry tomatoes, halved – about 150g
  • 8 whole green olives stuffed with pimento, 50g
  • 8 toothpicks, for the ā€œeyesā€

Instructions 

  • In a bowl, mash the avocado with lime juice, salt, and pepper to taste. This is your monster’s green gooey slime. Set aside.
  • SautĆ© red pepper strips in a skillet over medium heat with a little oil for about 3–5 minutes until softened and slightly caramelized. These make perfect wiggly monster tongues.
  • Skewer each stuffed green olive with a toothpick. These will go on top of the croissant as eyeballs.

Assemble the Monsters:

  • Slice each croissant horizontally (hinge-style if you can).
  • Spread the mashed avocado generously on the bottom half.
  • Add tofu scramble (your ā€œmonster brainsā€).
  • Place a few baby spinach leaves and some cherry tomato halves inside for juicy pops of red.
  • Hang one or two red bell pepper strips from the center as the tongue.
  • Gently close the croissant mouth, letting some filling show.
  • Stick two stuffed green olive ā€œeyesā€ on top of each croissant using toothpicks. Angle them outward or cross-eyed for silliness.
  • Serve immediately and enjoy your silly, savory monster!
