Turkey, Mushroom and Cheese Casserole

Cut the turkey into small pieces, dice or slice the onion into half-moons, thinly slice the mushrooms, and cut the tomatoes into wedges. Grate the cheese.

Combine the meat with the onion, mushrooms, and spices.

In a separate bowl, whisk together the egg, sour cream, and grated cheese.

Lightly grease a baking dish with vegetable oil, add the meat, mushroom, and onion mixture, and arrange the tomato wedges on top.

Pour the cheesy sauce evenly over the meat and vegetables.
