preheat oven to 400*. while oven is heating, start frying the ground beef and peppers/onions blend together.
while beef is browning, drain tomatoes and mushrooms, and open french bread tube.
spray a large cookie sheet with pan spray, and CAREFULLY find the edge of the bread roll (it looks like a "seam"). unroll the bread and lay it on your baking sheet. you may have to "patch a hole or two", or stretch the dough gently to fit your pan.
pour the pizza sauce over the dough, then start layering the ingredients, sprinkling the fire-roasted tomatoes, and mushrooms over the whole pizza evenly.
take the two shredded cheeses and pour them into a bowl together. mix them up with your hands, then top pizza (this seems to distribute the fat/nonfat cheese more evenly, and the melt on the pizza is good).
bake for 15 minutes and cut into 12 large pieces to enjoy! the count for this pizza per slice is: 165 calories, 3.5 grams fat, 19 grams total carbs! serve with a side salad and feel like you've splurged...
