Gotta try this with my bf

Ahhhhhh true. Like taco salad?

I was thinking more like those chip hats filled with sauce, but that's a fair comparison too.

My thoughts exactly. The flat open dough serves, as a plate/bowl with ingredients placed on top.
Calzone however, has two clear layers of edibleness, top and bottom.

I would consider pizza an open face sandwich. Like toast would be an open face sandwich.
