Crockpot Beef Stroganoff

Again, found a basic recipe on allrecipes.com but modified it in so many ways that I'm taking ownership.

1 lb. cubed beef stew meat
2 cans condensed golden mushroom soup (different than cream of mushroom)
1 onion, chopped
1 packet beef onion soup mix (Lipton makes this)
2 tablespoons Worcestershire sauce
1/2 cup water
1 teaspoon salt
1/2 teaspoon pepper
1 teaspoon garlic powder
12 ounces sour cream
*1/3 cup chopped green pepper (optional)
1-2 large bags egg noodles

In the crockpot combine the first 9 ingredients and stir. Cook on low for 6 hours. Right before you're ready to serve add sour cream. You can either mix in the noodles or serve them with the sauce on top.

I grew up with green pepper in my stroganoff. The problem is that if you put it in with the other ingredients, it adds a strong flavor to the sauce. I sautee the green peppers with some olive oil until they're soft and then add them with the sour cream.
