Instructions

1. Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper.
2. Thinly slice half the red onion. In a small bowl, toss the sliced onion with red wine vinegar and a pinch of salt. Set aside to quick-pickle.
3. Dice the remaining half of the red onion. Heat 1 tablespoon cooking oil in a skillet over medium heat. Add the diced onion and cook, stirring occasionally, until caramelized, about 8-10 minutes. Season with salt and pepper.
4. While the onion cooks, slice the long green pepper into thin rings. Remove seeds if desired. On the prepared baking sheet, arrange the flatbreads.
5. Spread 2 tablespoons BBQ sauce on each flatbread, leaving a small border around the edges.
6. Top flatbreads with the caramelized onions, pepper rings, and diced pineapple. Tear the fresh mozzarella into small pieces and scatter over the flatbreads. Sprinkle with shredded Monterey Jack cheese.
7. Bake for 10-12 minutes, until the cheese is melted and bubbly and the edges of the flatbread are golden and crisp.
8. Remove from the oven. Drain the pickled onions and scatter them over the flatbreads. Garnish with chopped cilantro. Slice and serve warm.
9. Drizzle with olive oil and add extra black pepper to taste if desired.
