Step 1

Preheat oven to 400°F. Spray a large 3-quart baking dish with non-stick cooking spray or olive oil. Set aside.

Step 2

Slice chicken breasts in half horizontally to make them thinner, lightly coat them in olive oil and place on a baking sheet. Liberally season with salt and pepper and bake for 20 minutes.

Step 3

While the chicken is baking, heat the bags of frozen cauliflower rice and broccoli according to package instructions. Discard any excess water or moisture.

Step 4

Remove chicken from oven and let cool for 5 minutes. Carefully chop baked chicken into bite-sized pieces.

Step 5

In a large bowl, add cooked cauliflower rice, broccoli, chicken, eggs, mozzarella cheese, salt, garlic powder, onion powder and butter. Toss together until fully combined.

Step 6

Transfer casserole mixture to the prepared baking dish and top with the remaining Italian blend cheese.

Step 7

Bake for 50 minutes, until the cheese on top has fully melted and started to brown slightly. Let cool for 10 minutes before serving.
