This recipe is from my 1970 and 1976 Campbell Soup Cookbook (Cooking with Soup). The added ingredient that makes these sloppy joes taste good, is the chili powder (providing you add 1-1/2 tsp). We enjoyed our sloppy joes topped with a bit of shredded sharp cheddar cheese.
Campbell's Soup Sloppy Joes
1 lb. ground beef
1 cup diced onion (I only added 3/4 cup)
1 cup thinly sliced celery (I only added 1/2 cup)
1 tablespoon shortening
1/2 teaspoon salt
1/8 teaspoon ground black pepper
1 teaspoon chili powder (I added 1-1/2 teaspoons)
1 (10-3/4 ounce) can condensed tomato soup
5 hamburger buns
shredded cheddar cheese, to garnish sloppy joes (opt.)
In a large skillet, brown the ground beef, onion, and celery in the shortening. (I used 85% ground chuck for this recipe, so I didn't have to add any shortening when cooking the beef and vegetables.) Drain off the excess grease.
Season the cooked beef and vegetables, with the spices.
Stir in the tomato soup.
Cover skillet, and simmer to blend flavors. (I simmered mine for 30 minutes; stirring frequently.)
Serve sloppy joes on hamburger buns topped with some shredded cheddar cheese, if desired.
Note: I thought the sloppy joes tasted even better reheated the next day. You could really taste the chili powder in the sloppy joes a bit more.
