Preheat a skillet with a few tablespoons of light olive oil. Pop your raw meatballs on the skillet. To turn the meatballs, lift up the skillet and shake it from side to side. This will help your meatballs keep their round shape.
Add butter to the same skillet you friend the meatballs in. Once butter is melted, add flour to the butter and stir until well combined.
