Beef and Noodles / Easy Stroganoff

My adaptation of a stroganoff recipe. It's grown up enough for the adults, but my 4-year old likes it too. Only takes about 45 minutes with very little work.

• Ready In: 45 mins
• Serves: 4

Ingredients

• 1 -1 1⁄2 lb  sirloin
• 1 (16 ounce) package  wide egg noodles
• 1 (10 1/2ounce) can  cream of mushroom soup or 2 (10 1/2ounce) cans  cream of mushroom soup
• 1  medium onion, chopped
• 1 (8 ounce) can mushrooms
• 2  tablespoons sour cream
• 1⁄2-1  cup water
• 1  tablespoon  oil

Directions

1. Slice sirloin in bite sized pieces and set aside.
2. Chop onion and set aside as well.
3. Start noodles boiling.
4. In another pan brown sirloin in oil.
5. When meat is cooked through add onion and mushrooms; sauté until onions are translucent.
6. Add can of cream of mushroom soup (for more sauce or thinner sauce add 2nd can of soup).
7. Simmer until the noodles are done or desired consistency is achieved (should be a fairly thick sauce).
8. If needed add water to thin sauce.
9. Right before serving add the sour cream.
10. *I keep the noodles and sauce separately so everyone can choose their own amount of sauce, but this can be mixed together in a casserole dish for serving at the table).
