Cut the florets from the stems and cut them into small bite-sized pieces. Trim off the dry, tough end of each stem (about ½ inch) and discard. Use a vegetable peeler to remove the fibrous outer layer from the stems. Once peeled, finely slice the stems into matchstick-size pieces.
In a large mixing bowl, combine the prepared broccoli florets and stems, green onions, apple matchsticks, raisins, and slivered almonds.
In a small bowl, whisk together the vegan mayonnaise, apple cider vinegar, maple syrup, Dijon mustard, garlic powder, salt, and pepper until smooth.
Pour the dressing over the salad ingredients and toss well to coat evenly.
For enhanced flavor, refrigerate the slaw for 20–30 minutes before serving.
Serve cold or at room temperature.
Notes
Transfer any leftover broccoli slaw into an airtight container and store it in the refrigerator for up to 3 days. Give it a good stir before serving. The broccoli will soften a bit towards the end of this time, but it’s still delicious!
