Let's start this flatbread pizza by pre-heating that oven to *400. Pop open the roll of dough and stretch it thin. Not see-thru thin, but about the size of a jelly roll pan. Grab a spoon and spread your salsa over the dough. Sprinkle 1/2 of the shredded cheese right over the salsa. Layer on your chicken, peppers and onion. Now cover that flatbread pizza with the remaining cheese. Bake for 10 - 15 minutes depending on your oven. The cheese should be all melt-y gooey and the crust is a nice golden brown around the edges. Top it off with the cilantro and you're ready to eat!
