My favorite is the philly steak pizza dominos and I used to order that all the time. One that I really would like to try is the macaroni and cheese pizza which seems weird but sounds so good too. I love macaroni and cheese so that will be a nice combination on a pizza for me.
I'm not into cheesesteaks but I'm not too hard to please with pizza. If it comes from a restaurant and it has meat on it I'd probably eat it. The weirdest I probably ate though was BBQ chicken. My favorite place is actually Pizza Hut because they have stuffed crust.
