Millionaire's Cottage Pie

Add raw, peeled potato chunks to a pot of water and submerge them.

Shred cabbage and slice leeks, then stir‑fry them together in a skillet.

Dice carrots and onions and add them to the skillet, cooking until softened.

Add ground beef to the sautéed vegetables and brown it.

Sprinkle flour over the meat and vegetable mixture and stir to combine.

Pour tomato sauce and a splash of liquid into the pan, then add dried herbs; simmer briefly.

Stir in green peas to the meat mixture.

Mash the boiled potatoes, then fold in sliced leeks, butter, and black pepper.

Spread the mashed potato mixture in a baking dish, top with the meat‑vegetable filling, and finish with a generous layer of grated cheese.

Bake until the cheese topping is golden and bubbly, then serve.
