I swiped this recipe from my absolute favorite neighbor, M, and then modified it somewhat.
1 box of organic Tomato Soup
1 jar of organic Marinara Sauce
6 oz or so of elbow macaroni
2 cups or so of frozen corn kernels (or other small vegetables)
Bring the soup and sauce to a simmer in a large-ish sauce pan. Once simmering, dump in the macaroni and vegetables, cover, and simmer til the pasta is done.
Optional: plop in some frozen meatballs in the beginning if you want some meat.
