To a large pot on the stove over medium high heat add in the sausage and onion break the sausage up and cook it through.
Remove any excess grease from the pot. Add in the pasta, mixed vegetables, bouillon cubes, water, pasta sauce, tomato paste, and seasonings, stir well. Bring up to a simmer then turn the heat to low let simmer for 12 to 18 minutes, stirring occasionally (so the pasta doesn’t burn) until the pasta is tender if the liquid line gets too low while simmering add 1/2 cup of water in at a time until the pasta is cooked.
