Notes

• For a vegetarian version, substitute ground beef with lentils or a plant-based meat alternative and use vegetable broth.
• Feel free to add other vegetables like mushrooms or green beans based on preference.
• To save time, use store-bought pre-made mashed potatoes but ensure they are seasoned well.
• The cheddar cheese topping is optional; Parmesan or mozzarella are good substitutes if preferred.
