Transfer the peppers to a heavy paper bag, close the top of the bag, and let the peppers cool for about 20 minutes.
When the peppers are cool enough to handle, remove the cores and peel away the skins. With paper towels, wipe away the seeds -- do not rinse the peppers under running water to remove the seeds, or you will lose the flavorful juices. Cut the peppers into thin strips and place them in a bowl along with any juices.
Heat 2 tablespoons of the olive oil in a sauté pan over medium-low heat. Stir in the onions and cook, stirring occasionally, until very soft and glazed, about 5 minutes. Raise the heat to high, stir in the vinegar, and simmer until most of the liquid has evaporated. Add the onions to the bowl with the peppers. Stir in the soppressata and salt, cover, and set aside.
Preheat the oven to 425°F.
Lightly spray two 16-inch pizza pans with olive oil spray and set aside.
Punch down the dough and turn it out onto a lightly floured surface. Knead the dough for 3 to 4 minutes, until smooth and no longer sticky. Divide the dough into 4 equal pieces, and shape each piece into a ball. Set 2 balls aside and cover them with a towel or bowl.
Roll one piece of dough into a 16 1/2-inch round. Place the dough on one of the pizza pans. Spread half the pepper mixture evenly over the dough.
Scatter half the rosemary needles over the work surface. Place the second piece of dough on top of the rosemary and knead the needles into the dough. Roll the dough out into a 16-inch round and place it over the pepper mixture. Tightly seal the edges of the focaccia by folding the edges of the bottom dough up to meet the edges of the top dough and pinching the edges together to seal them. Brush the top of the focaccia with 1 tablespoon of the olive oil and sprinkle with coarse salt. Using scissors, cut an X in the center of the top of the focaccia.
Repeat the process with the remaining dough and filling ingredients.
Bake the focaccia for 25 to 30 minutes, until the top and bottom are browned.
Cool the focaccia slightly, then use scissors or a sharp knife to cut the focaccia into wedges.
