How about a beef stew you can make ahead in the crockpot? Serve with good crusty bread and a nice salad and you're done!
I make my beef stew with cubes of beef chuck that I lightly dredge with seasoned flour and lightly sautee first. Dump this is the crockpot with a cup of red wine and a cup of beef stock. Season with rosemary, thyme, pepper and garlic. Add some onions, small potatoes, mayeb carrots or celery? Cook for 6 hours and voila! Delicious.
