I have a crock-pot recipe that is basically a simple beef stroganoff recipe.
I doubled the recipe and changed it a little, so here's how I make it:
4 pounds round steak browned
2-3 cans cream of mushroom soup
1 small can mushroom stems and pieces (use the juice in the can)
Your favorite seasoning, I use garlic herb mix (no measurement, I just sprinkle)
Egg noodles
I dump the can of mushrooms, juice and all into the bottom of the crock pot, then layer with meat and soup to the top, usually seasoning about each meat layer. I cook all day on low.
[warning - the soup gets to looking pretty gross mid-day, but it does becomes a nice sauce when it's done, may need a little stirring.] Serve over cooked egg noodles.
I cut the left-over meat up into bit sized pieces, throw in the left-over noodles and sauce add frozen peas; and you have beef and noodles all ready for another meal.
