Boil peeled potatoes in salted water until tender (approx. 15-20 mins). Drain well.

Mash potatoes with butter while hot. Let cool slightly, then mix in egg, milk, chopped dill, salt, and pepper until smooth and firm.

Preheat oven to 400°F (200°C) and line a baking sheet with parchment paper.

In a skillet, sauté onions and peppers in oil until soft. Add ground beef and cook until browned.

Stir in garlic, tomato paste, and spices to the beef. Cook 2 more minutes. Remove from heat.

Scoop mashed potatoes onto baking sheet. Form into nests by creating a well in the center of each mound.

Fill each nest with the beef mixture and top generously with shredded cheese.

Bake for 15-20 minutes until cheese is bubbly and potato edges are golden brown. Garnish with fresh herbs and serve.
