My mom used to call this snow day soup - perfect with crusty bread to dip. It freezes/reheats really well. Makes 6-8 servings.
1 pound lean ground beef or turkey
1 onion, diced
5 cups water
salt and pepper to taste
28 ounce can tomato sauce
1/4 tsp. red pepper flakes
approximately 28 ounces frozen cubed potatoes
Brown beef/turkey and onion in the same pan; drain the grease.
Add all other ingredients in a large pot with a lid. Bring to a boil, then add the beef/turkey and onion. Reduce heat to medium-low and cook for 1-2 hours until the potatoes are tender and the soup has gotten thicker.
