Sometimes you want a big, restaurant-style burger and sometimes you want a MONSTER burger.
I had never made a stuffed burger before. Honestly? I have never even eaten one. So, these might have been too big, but my husband was thoroughly satisfied.
You could easily grill them but I chose to sear them in a hot cast iron skillet and then place them into the oven.
Toppings are truly your choice, but I cooked bacon, crumbled it, and allowed the bacon to rest on paper towels. Then, I removed all but about two tablespoons of the bacon drippings from the pan, and added chopped mushrooms and onions. Once those were cooked, I placed the bacon back into the pan and kept it warm.
