Creating Poor Man’s Husband Casserole is straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Cook Meat: In a large skillet, heat the olive oil over medium heat. Add the chopped onion and minced garlic, cooking until softened. Then, add the ground beef or turkey. Cook until browned, breaking it apart as it cooks.
3. Add Vegetables: Stir in the frozen mixed vegetables and cook for an additional 5 minutes.
4. Combine Ingredients: In a separate bowl, mix together the cream of mushroom soup, milk, Worcestershire sauce, salt, and black pepper. Pour this mixture into the skillet with the meat and vegetables. Stir until well combined.
5. Layer Casserole: In a greased 9×13 inch baking dish, spread the meat and vegetable mixture evenly.
6. Top with Mashed Potatoes: Spoon the prepared mashed potatoes over the meat mixture, smoothing it out to cover evenly.
7. Add Cheese: Sprinkle the shredded cheddar cheese on top of the mashed potatoes.
8. Bake: Place the baking dish in the preheated oven and bake for 30-45 minutes, or until the cheese is melted and bubbly, and the casserole is heated through.
9. Cool: Remove from the oven and let it cool for about 10 minutes before serving.

These steps will guide you in creating this incredible casserole effortlessly.
