One of our favourite go-to quickies is sloppy joes, done the way my mother in law made them. Brown 1 pound of ground beef, drain fat, add a chopped onion and cook until soft, you can add some celery too if you like. Pour in 1 can of Chicken Gumbo soup (no water), 1/2 cup of chili sauce (or salsa if you want a bit of heat), 1 TBSP mustard. Heat through and serve on buns with potato chips and pickles on the side. This has been my DH's favourite since he was a kid and I like it too, so do my boys.
