Grilled pesto pizza with sweet potatoes, kale and balsamic reduction

I cheated a bit and bought store-made pizza dough, instead of electing to use Chloe's optional recipe. This recipe is a bit unusual in that you cook the pizzas on the stovetop in a griddle pan which (oops) I don't have (I have GOT to start reading recipes more closely before I start cooking.) They seemed to cook fine in a skillet though.

My guests loved the pizza, and so did I. It sat really heavy in my stomach though. I might try to reduce the oil in the pesto if I make these again. This recipe has numerous components and the pizzas have to be cooked one at a time (although I guess you could have multiple skillets going), so budget yourself 2-2.5 hours for this.
