Well, this was made during spring break, so while we remember eating the stromboli, we have no recollection of making it. ;)
The first one looks like shredded kale and roasted red bell pepper...
...with Daiya Mozzarella using our usual pizza dough, rolled a little thinner than usual.
Apparently, there was a second one made with mushroom, onion and Daiya Cheddar by the look of the picture at the top.
It was cooked lower and slower than pizza, probably something like 400° for 20-25 minutes. I do remember we had bought a huge batch of red bell peppers, which would explain the dipping sauce.
