1 pound cooked ground hamburger, seasoned to taste*
1 can cream of mushroom soup
1 can milk (you may need more depending on desired consistency)
1 packet onion soup mix
1 can sliced mushrooms (optional)
Combine all ingredients in a large skillet, cover and simmer for 10-15 minutes, stirring occasionally. Serve over rice or egg noodles.
*I like to buy a lot of hamburger in advance at a place like Costco or wherever it is on sale, cook up all the hamburger and then divide it into 1 pound portions. I put the cooked and seasoned hamburger in freezer bags and freeze it. It keeps really well and makes it really easy to add hamburger to recipes like this or any that call for cooked ground beef. When I use it in this recipe I just add it to the skillet frozen!
