I made this tonight and it was a HUGE hit. My 2 year old loved helping me too.
I used frozen pizza dough (half whole wheat) for a 12 in crust
I added: 3/4 can vegetarian refried beans, topped with a small can of mild rotel, sliced onions, a sprinkle of cumin, a sprinkle of oregano and topped with shredded cheese, the Mexican blend. I baked at 450 for about 10 minutes. I baked it too long and the crust was too crunchy.
It was really tasty and super filling, we had it with edamame and peas.
