In Mexico, this dish is served for breakfast; stateside, families enjoy it as a quick and tasty dinner, too. Follow the make-ahead directions and heat the frozen casserole in a microwave for a meal that's ready in minutes.
The key to making these meatballs is to brown them first in a skillet and then braise them in a sauce of red wine and tomatoes. Serve them with crusty bread or spaghetti to sop up the sauce.
