Beef Stroganoff

I make a version of beef stroganoff that is very easy and very yummy!

1 package of wide egg noodles
1-2 packages of beef for stew (the kind that is already cut up in cubes)
1 package of mushrooms (I get the ones that are already cut so it is less prep time)
1 small container of sour cream (8 oz)
1 small to medium sized yellow onion sliced
oil

Bring up a pot of water to boil to cook noodles. Coat a large pan (with sides) with oil and brown the beef on both sides. Once beef is brown take it out of the pan and add the onion and let carmelize. Once onions are nice and golden brown add in mushrooms. Cook mushrooms down and add in container of sour cream and salt and pepper. Add beef back in and bring to a boil. Cover and simmer for about 10-15 min or until the noodles are ready. If the sauce is not thick enough for your liking you can add a little cornstarch to thicken it up. Serve over noodles and enjoy!
