Place zucchini and yellow onion in food processor using the shredding attachment and shred. Place in a couple paper towels and squeeze out all the excess liquid. So annoying, but you have to do it!
Place zucchini and onion in a bowl, mix well with almond flour, egg, garlic cloves, garlic powder, salt and pepper.
Use an ice cream scoop to scoop out the mixture and place into 7 muffin cups. I used silicone muffin liners, if you don’t, be sure to heavily grease each muffin tin to keep it from sticking.
