Real easy....
Take one medium onion, peel it and slice it about 1/4" think
Lay complete slices on the bottom of a slow cooker (crock pot) cover the entire bottom.
Put 2" chunks of venison on the onion (I use about 2 to 2 1/2 lbs)
Pour over the top of the meat:
1 can chedar cheese soup
1 can golden mushroom soup
1 can french onion soup
Don't stir!
Turn slow cooker on high and let simmer about 4 hours.
Throw in two 16 oz bags frozen stew vegitables.
stirr.
Let it go about 4 more hours or until the potatoes are soft.
Get a spoon and STAND UP AND EAT!!!

There are plenty of variations to this... you can use a roast instead of chunks. You can use fresh vegies instead of frozen (but the frozen are so convient).
ENJOY!!
