1
Season tomatoes with 1/8 teaspoon garlic powder and 1/8 teaspoon onion powder (or more to taste).
2
Bring a large skillet sprayed with nonstick spray to medium-high heat. Add broccoli slaw and 1/2 cup water. Cover and cook until fully softened, 10 to 12 minutes. Uncover and, if needed, cook and stir until water has evaporated, 2 to 3 minutes. Transfer to a microwave-safe bowl, stir in 3/4ths of the seasoned tomatoes, and cover to keep warm.
3
In a wide bowl, mix crushed cereal with Italian seasoning, remaining 1/8 teaspoon garlic powder, and remaining 1/8 teaspoon onion powder.
4
Place egg whites or substitute in another wide bowl. Coat chicken with egg, shake to remove excess, and coat with crumbs.
5
Re-spray skillet and return to medium heat. Cook chicken for 5 minutes per side, or until cooked through.
6
Top chicken with remaining tomatoes, and sprinkle with cheese. Cover and cook for 2 minutes, or until cheese has melted. If needed, reheat saucy slaw in the microwave.
