I got this recipe from my aunt at my sister's bridal shower. It was a sort-of game where we had to guess the missing ingredients. So I just found it the other day and since we had a fryer chicken in the freezer I decided to see if I could modify it slightly to go in the crock pot. This is what I came up with:

Viennese Chicken

Cook together in large pan:
2 Tbsp. Butter
1 minced onion

When the onion is yellow add:
2 T. Canola oil or Extra Virgin Olive Oil would probably work well too
1 green pepper, chopped
6 mushrooms, chopped

When vegetables are all sauteed, dump those in a crock pot along with:
1 roasting chicken, cut into pieces
1 can chopped tomatoes
1 can chicken broth
1 can tomato soup
1 Cup water
Salt, Paprika, and I added some Pampered Chef Greek Seasoning, but I think anything with garlic and something that goes well with poultry would probably work well here. You might have to get a little creative with the spices.

Cook on high 4-5 hours or so. About 30 minutes before you take it out, mix together:
1 Tbsp. flour
1/2 Cup Sour Cream

Stir into the chicken and sauce.

Serve over rice or mashed potatoes.

It turned out pretty tasty although I think with the skin on the chicken it was a little greasy. Maybe next time I wouldn't add the chicken broth from the can. If you need extra moisture, I think a little extra water with a little salt would probably work just fine. The tomato soup isn't in the original recipe, but I added it for flavor and moisture. I might consider using chicken breast next time to make it lower in fat. Let me know if you try it!
