1. In a skillet, melt butter and saute onion until no longer opaque (you can adjust the amount to 1/2 onion if your family doesn't love onions like mine). 2. Slice mushrooms and add, cooking until done. (You may substitute a 4 oz. can of mushrooms, drained.) 3. While onions are cooking, mix ground beef, eggs, bread crumbs, Worcestershire sauce, salt and pepper. Stir well. 4. Tear off a sheet of aluminum foil, approximately the size of a 9x13 pan. 5. Spread meat mixture onto foil in the shape of the rectangle. Place cheese slices down the middle crosswise (down the short center). Pour on onions and mushrooms. 6. Fold edges of meat in towards the center. Seal seam. 7. Flip the meat over into a baking dish, such as a 9x13 glass dish, seam side down and make sure ends and seams are sealed and no filling is exposed. 8. Bake in a 350 degree oven for 45-55 minutes. This can be served alone, with ketchup (for a burger taste), or even with brown gravy, if desired. ---------------------------------------------------------------------------
