Italian Sausage And Bean Soup With Pasta

1 pound Italian sausage
1 cup onion, chopped
2 tsp olive oil
28 ounces diced tomatoes
1 cup pasta (shells, penne, ziti, or other sturdy pasta)
2 chicken bouillon cubes
3 1/2 cups water, hot
18 ounces kidney beans, drained

Brown the sausage and onion in the oil in a large skillet over medium high heat for approximately 5 minutes. 

Once the sausage and onion have been browned, add the tomatoes with their juice, the pasta, bouillon cubes, and water.  Bring to a boil, reduce the heat, then add the kidney beans.

Make sure soup is just simmering, then cover pot, and simmer for about 10 to 15 minutes or just until the pasta is al dente.
