1. Preheat oven to 450 degrees Fahrenheit (230 degrees Celsius).
2. Mince onion with a kugel blade (the grater piece with rounder holes) and add eggs, salt, and pepper. Change to an S blade and finely chop the cauliflower or broccoli. Mix well.
3. Spray muffin top tins with cooking spray. If you don’t have muffin top pans, you can use regular muffin pans filled with a heaping tablespoon of mixture. Fill cavities till the top (latkes will shrink). Spray once more with cooking spray.
4. Bake for 15 minutes. Lower to 425 degrees Fahrenheit (220 degrees Celsius) and bake for about half an hour or until golden brown and crispy.
