it was good
My husband and son LOVED this burger. The addition of the mushrooms to the bacon-onion filling brought this burger up a notch. They both said they can't wait to have it again! I made only 6 large burgers instead of the 8 indicated.
I make this with the Cheesy Onion Burger Buns, a recipe also from this site. Every one loves this recipe and because of the awesome flavors you dont need all the condiments and stuff. Make sure when you put the bacon in the patty that you put it in the center leaving room around the edges to seal, otherwise they will fall apart while cooking.
