Mexican Pizza

Recipe and more appetizing pic here.  All in all, pretty tasty.  I just used regular pizza crust rather than the "pizza bases" called for in the recipe.  I assume the pizza base refers to something like a Boboli, but those have dairy in them so I went with my old standby pizza crust.  The only other mod I'll make in the future is to thin the refried bean mixture, as it was hard to spread on the dough and then it dried and became kind of cakey in the oven.  But, really, how bad could any pizza be?
