Prepare the Meatballs: In a large bowl, combine the minced meat, onions, garlic, egg, breadcrumbs, parsley, cumin, black pepper, paprika, thyme, nutmeg, and salt. Mix well until all ingredients are evenly distributed.

Shape the mixture into small meatballs or patties, as desired.

Cook the Meatballs: In a large skillet, heat the olive oil over medium heat. Add the meatballs or patties and cook until browned on all sides and cooked through, about 10-12 minutes. Remove from the skillet and set aside.

Make the Sauce: In the same skillet, add 2 tablespoons of flour and cook, stirring constantly, for about 1 minute.

Gradually add the milk, continuing to stir to avoid lumps, until the sauce thickens, about 5-7 minutes.

Combine and Serve: Return the meatballs or patties to the skillet, ensuring they are coated in the sauce. Simmer for another 5 minutes.

Garnish with additional chopped parsley before serving.
