Traditional Shepherd's Pie with Lamb

Peel the potatoes, cut them into cubes, and boil them in salted water until tender.

Once the potatoes are cooked, drain them, then add the milk and butter. Mash thoroughly until you get creamy mashed potatoes. Season with salt and pepper to taste.

Dice the red onion, carrots, and celery stalks. Heat the olive oil in a pan, add the minced lamb, and sauté until browned (approx. 10 minutes). Add the chopped vegetables and crushed garlic, then continue to sauté together.
