Preheat the oven to 400 degrees.
Cook the riced cauliflower and broccoli according to the package instructions and let cool slightly.
Use a strainer to squeeze as much liquid out of the riced vegetables as possible.
Put the riced veggies into a mixing bowl with the shredded cheese, almond flour, garlic powder, egg and salt and pepper to taste. Knead with your hands until thoroughly mixed.
Form the mixture into 15 evenly sized balls and flatten them slightly in your hands into rounds.
Place the rounds onto a parchment lined baking sheet, and bake for 15-20 minutes until golden brown and crispy.
