      • 2 pounds skinless boneless chicken breasts
      • 1 tablespoon olive oil
      • 2 10-ounce bags of frozen cauliflower rice (or 1 head of cauliflower, riced and cooked)
      • 1 16-ounce bag frozen broccoli cuts
      • 2 large eggs, whisked
      • 3 cups, shredded mozzarella cheese
      • 2 teaspoons kosher salt
      • 2 teaspoons garlic powder
      • 2 teaspoons onion powder
      • 2 tablespoons unsalted butter melted
      • 1 cup shredded Italian blend cheese


      • Preheat oven to 400°F. Spray a large 3-quart baking dish with non-stick cooking spray or olive oil. Set aside.
      • 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.
      • While the chicken is baking, heat the bags of frozen cauliflower rice and broccoli according to package instructions. Discard any excess water or moisture.
      • Remove chicken from oven and let cool for 5 minutes. Carefully chop baked chicken into bite-sized pieces.
      • 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.
      • Transfer the casserole mixture to the prepared baking dish and top with the remaining Italian blend cheese.
      • Bake for 50 minutes, until the cheese on top has fully melted and started to brown slightly. Let cool for 10 minutes before serving.
