We have been making these for years! They are my favorite burger! Ssssh...sometimes we use a packet of LIPTON onion soup mix. Delicious!!
We make these burgers a lot during the summer. A lot. What makes them even better is melted swiss and carmelized onions and mushrooms. When we make them, the whole neighborhood comes to check them out. They just HAVE to know what smells so good!
This was awesome! I also used the dry soup mix... put some in the hamburger meat (along with some minced garlic) b4 I cooked them. YUMMY!!!
