It’s OK to stir and flip the meatballs at the same time, as this step requires only 10 minutes on medium to low heat. While meatballs are browning pour tomatoes in a blender or food processor and pulse about 5 seconds (IMPORTANT: don’t let the the tomatoes blend all the way, you want them choppy). When the meatballs are browned add the tomatoes, tomato paste, minced garlic, sugar, paprika, salt and black pepper to taste. Let the sauce simmer for about 20-25 minutes until sauce thickens. Add more salt, sugar or pepper to your liking.
