Peel and chop the potatoes, then boil them in a pot with enough water to cover them until fully cooked.

While the potatoes are boiling, finely chop the vegetables (onion and tomato).

Heat a frying pan, add butter or oil, and sauté the chopped vegetables and ground beef. Season with salt, pepper, basil powder, and garlic powder. Cook until everything is fully cooked.

Add flour to the pan and cook for a few more minutes until the mixture thickens and most of the liquid is absorbed.

Drain the boiled potatoes, place them in a bowl, and mash them thoroughly. Add a small amount of salt and pepper for seasoning.

In an oven-safe dish, layer the cooked meat and vegetable mixture evenly, pressing it down firmly.

Spread the mashed potatoes evenly over the meat layer, pressing down gently.

Top with a generous amount of cheese. Use Emmental, Cheddar, or Mozzarella based on preference.
