Instructions

  1. Preheat oven to 450°F. Line a baking sheet with foil (for 4 servings, use two sheets). Wash and dry all produce. Halve, peel and thinly slice the red onion. Drain the pineapple over a small bowl, reserving the juice. Stir ¼ of the sliced onion, half the red wine vinegar and a pinch of salt into the bowl with the pineapple juice. Set aside to quick-pickle.
  2. Heat a drizzle of vegetable oil in a large pan over medium heat. Add the remaining sliced onion and cook, stirring occasionally and adding splashes of water as needed to prevent sticking, until softened, 6-8 minutes.
  3. While the onion cooks, halve the poblano pepper, remove the seeds and ribs and slice into thin strips. Toss the poblano strips in a small bowl with a drizzle of olive oil, salt and pepper. Dice the fresh mozzarella into ½-inch pieces. Finely chop the cilantro.
  4. Once the onion is softened, increase the heat to medium-high. Add the drained pineapple and another drizzle of vegetable oil. Cook, stirring, until the pineapple is lightly browned, 2-3 minutes. Stir in the remaining red wine vinegar and cook until the onion and pineapple are caramelized and jammy, 1-2 minutes more. Season with salt and pepper, then remove from heat.
  5. Brush or rub each flatbread with a drizzle of olive oil. Remove the preheated baking sheet from the oven and carefully place the flatbreads on it (for 4 servings, divide between two sheets). Spread each flatbread evenly with BBQ sauce, then top with the caramelized onion and pineapple, poblano strips, Monterey Jack cheese and diced mozzarella.
  6. Return the flatbreads to the oven (top rack; for 4 servings, use top and middle racks and swap positions halfway through). Bake until the cheese is melted and the edges are golden brown, 10-12 minutes. Transfer to a cutting board, top with chopped cilantro and pickled red onion (drained) to taste. Slice and serve.

Recipe Tips

For extra crispy flatbreads, preheat the baking sheet in the oven before adding the flatbreads.

If you prefer a milder flavor, remove the seeds and ribs from the poblano pepper completely.

The pickled onion can be made ahead and stored in the refrigerator for up to a week.
