Try this Stuffed Pepper Soup I Recipe
Canned tomato sauce provides the primary liquid base that prevents the ground beef from scorching on the bottom of the Dutch oven during the initial simmer. Without the natural acidity and pectin found in a 29-ounce can of standard tomato sauce, the starches from the rice and the proteins from the beef create a dense, muddy emulsion instead of a brothy soup.
Thick-walled heavy bottomed pots ensure even heat distribution while simmering on low. Monitoring the moisture level prevents burning when using large cuts of vegetables.
