Follow these easy steps to create your super easy dinner casserole:

1. Preheat Oven: Preheat your oven to 350°F (175°C) to prepare for baking.
2. Mix Ingredients: In a large bowl, combine the cooked protein, cooked pasta or rice, frozen vegetables, and cream of mushroom soup. Stir until well mixed.
3. Transfer to Casserole Dish: Pour the mixture into a greased 9×13 inch casserole dish. Spread evenly to ensure even cooking.

5. Bake: Place the casserole in the preheated oven and bake for 30-40 minutes, or until the cheese is melted and bubbly.
