Thoroughly mix ground beef and italian sausage together and shape into bite-sized meatballs. Fry meatballs in large skillet, turning frequently, until browned. Drain fat from meatballs.
You may cook this soup in a large crockpot, or in a large kettle on top of the stove.
Place the meatballs, beans, tomatoes, diced onion, minced garlic, beef base, italian seasoning, parsley, and water into crockpot, on high heat. (If using a kettle on the stove, cook on medium heat)
When soup is simmering in the crockpot (about 2-3 hours), add in the tortellini and the italian vegetables. Soup will need to be brought back up to a good simmer before serving. (If using a kettle, add tortellini and italian vegetables after soup has boiled for about 15 minutes. Return soup to a boil, reduce heat, and let simmer for about another 30 minutes before serving.)
I serve this hearty soup with a nice heated loaf of Italian or French bread, warmed hard rolls, or sometimes garlic toast.
