Steam cauliflower for 5 minutes on stovetop. Drain thoroughly and use paper towel to blot away excess water.
Pull apart florets then mash cauliflower in a bowl. Crush Cheerios in a sandwich bag.
Combine cauliflower, Cheerios, parmesan cheese, mozzarella cheese, egg and thyme until thoroughly mixed.
Form mixture into tightly packed nuggets. Place nuggets on a baking sheet. Drizzle nuggets with olive oil for extra crunch. Bake each side for roughly 10 minutes or until golden brown. Enjoy!
