Skillet Meatballs with Vegetables and Mushrooms

In a bowl, combine the ground meat, grated onion, egg, breadcrumbs, and spices.

Roll the mixture into small meatballs, slightly smaller than a walnut.

Heat vegetable oil in a skillet and sear the meatballs until golden brown.

Transfer the meatballs to a plate.

In the same skillet, sauté the onion and garlic for 1 to 2 minutes. Add the mushrooms and bell peppers, and continue cooking.

Stir in the tomato paste and spices, mixing well.

Pour in a splash of water, cover with a lid, and simmer over low heat until cooked through.

Top with grated cheese, cover the skillet, and let the cheese melt.
