You can experiment with various beef recipes...
One we often do is to dump a can or two of mushroom soup and a packet of onion soup mix over a cheap roast, add a little water, and let it simmer all day. At night you shred the beef and serve over rice or noodles. Easy meal - just heat up a vegetable to go with.
Alternatively you can put a couple cans of tomatoes and some Italian spices in with your roast, and have that over rice.
Or there's taco meat: brown a bunch of hamburger, put it in the slow cooker, dump a jar of salsa over it, and let that cook. Serve it with tortillas and lettuce and cheese and whatever you'd normally have with tacos. Turns out pretty good.
Barbeque sauce with a roast or hamburger works, too.
None of this is haute cuisine, but if you're in a hurry...
Thank You so much.
Add a cup or two of coffee to that roast and your gravy will be out of this world!
BBQ sauce works well with country-style ribs, too.
It takes slightly more work, but chicken & dumplings is pretty easy. Cook one cut-up chicken, barely covered by water, all day (you'll probably want to add various chicken-related herbs, spices and/or seasonings). When you get home, fish out the chicken pieces, and strip the meat away from the bones, skin, and fat. Return the meat to the pot, add a couple of cups of frozen veggies (peas and carrots are classic), and spoon one recipe's worth of biscut mix (like Bisquick) on top. Let cook on high for another 45 to 60 minutes.
