These were okay.If I make them again,I will substitute some ground sausage for some of the hamburger and use canned pizza or spaghetti sauce for the plain tomato sauce to give it more of a "pizza" flavor.I used sliced olives instead of mushrooms(my kids aren't crazy about mushrooms)It was quick and easy to make.Just add a green salad and it is an easy meal.
A wonderful tasting sandwich. The kids go crazy for and so easy to prepare.
We ate these all the time as kids. My mom just mixed up the burger with aa the sauce, cheese and seasoning and put it on the buns RAW and let the meat cook in the oven. I cook the meat 1st now!
