Sloppy Joes

1 pound ground beef
1/2 cup chopped onion
1/2 cup condensed tomato soup
1/2 cup ketchup
3 tablespoons grape jelly
1 tablespoon brown sugar
1 tablespoon cider vinegar
1 tablespoon mustard (I use a deli/fancy style mustard. Not a yellow mustard. Yuck!)
1/2 teaspoon salt
1/2 teaspoon celery seed
5 hamburger buns, split

In large skillet, cook beef and onion over medium heat until meat is no longer pink; drain. Stir in the soup, ketchup, jelly, brown sugar, vinegar, mustard, salt and celery seed. Bring to a boil. Reduce Heat; simmer, uncovered, for about 10 minutes or until heated through. Serve on buns.

I like to eat mine open sandwich style with a fork and knife.
