This is just like the sloppy Joe recipe I grew up on and it is so good. We always browned the hamburger and onion and then drained the fat off before adding the mustard and ketchup. Then let that simmer a few minutes before adding the chicken gumbo soup. salt and pepper. We didn't add any more water because the soup has plenty. Let it simmer about 15 minutes and serve on buns or open-faced on sliced bread works if you don't have buns. Very good heated up later too.
