The green items are pepperoncini, or banana peppers. They're not sharp, and not exactly sweet, but you would probably enjoy them
@Winterybella. I sliced them and added the juice and seeds, as well as the peppers themselves. The pizza was so good that I will probably make another today or tomorrow. I only used a bit of sauce, and had that leftover from my last pizza, so I have a whole jar left over for my next few pizzas. I like how rustic the homemade pizzas are.
Incidentally, I forgot to mention that I ended up adding a few small scoops of flour, because it was just too soft and sticky. That amounts to about 1/2 cup more of flour, but I'd start off with the recipe's amount, and then add what you need.
@Corzhens I don't know the science of it, but I think the milk and baking powder gave it a little lift. The recipe does call for it to sit for about 10 minutes, so I think they act as a leavener in some fashion. It wasn't thick or heavy at all, in fact, it was somewhat more of a thick cracker consistency, which I really enjoyed.
