My DH favorote is Beef Stew in the Slow Cooker.
Beef cubes (you can buy them cubed or cube your own)
1 pack lipton onion soup mix
ittalian seasoning (to taste)
2 cans beef stock
2 cans water
whatever veggies you like in your stew - I use potaos and carrots
brown the beef
combine all ingerdients in crock pot/slow cooker
cook on low overnight (or throughout the day while you are gone)
It is delicious
Although hig in sodium. If you can't have that much sodium, just use water instead of stock. Or use tomato soup.
