Make Meatballs - In a large bowl, combine wine with breadcrumbs. Once softened, mix in lamb meat with eggs, garlic, salt and pepper. With your hands, form 12 meatballs per-pound of meat. If using for tapas or a cocktail party, roll into about 30 smaller balls or-so per pound of meat.
Cook Albondigas - Heat oil in a large casserole over medium-high heat and brown meatballs on all sides in batches. Once brown, transfer to a paper towel-lined plate. Add onions and cook 2-3 minutes until wilted. Pour in brandy and deglaze bottom of pan. From a distance, light brandy on fire to burn off its alcohol. When flame has subsided, add back meatballs and mix in broth, mint, and tomato sauce. Season with salt and pepper, cover, and cook over low heat for 45 minutes.
Serve - Place everything in a serving bowl and serve with mashed potatoes or rice, along with a green vegetable and crusty bread. If using as a tapas, place in a crockpot to keep warm and keep plenty of crusty bread around for sopping up the delicious sauce.
