Remove broccoli stems and set aside. Chop broccoli into small florets.

Step 2

Attach the shredder blade to a food processor. Shred 1/2 of the broccoli stems and 1/2 of the carrots. Switch to the slicer blade and slice remaining broccoli stems and carrots. Dump contents of the food processor bowl into a large bowl with broccoli florets and onion.

Step 3

Whisk together mayonnaise, olive oil, vinegar, and lemon juice in a small bowl. Pour in with the veggies and toss to coat. Marinate in the refrigerator for at least 1 hour.

Step 4

Taste and season with salt. Add sunflower seeds just before serving.
