Instructions

  1. Preheat the oven to 450°F. Line a baking sheet with foil and place it on the top rack. (For 4 servings, use two foil-lined sheets on top and middle racks.) Wash and dry all produce.
  2. Halve, peel and thinly slice the red onion. Drain the pineapple over a small bowl, reserving the juice. Stir one-quarter of the sliced onion, half of the red wine vinegar and a pinch of salt into the bowl with the pineapple juice. Set aside to quick-pickle.
  3. Heat a drizzle of cooking oil in a large pan over medium heat. Add the remaining onion and cook, stirring occasionally and adding splashes of water as needed to prevent sticking, until softened, 6-8 minutes.
  4. While the onion cooks, halve, core and very thinly slice the poblano pepper into 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.
  5. Once the onion is softened, increase the heat to medium-high. Add the pineapple and a drizzle of cooking 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.
  6. Brush or rub each flatbread with a drizzle of oil. Remove the preheated baking sheet from the oven and carefully place the flatbreads on it. (For 4 servings, divide flatbreads between both prepared sheets.) Spread the flatbreads evenly with BBQ sauce, then top with the caramelized onion and pineapple, poblano strips, Monterey Jack cheese and diced mozzarella.
  7. Return the flatbreads to the top rack and bake until the cheese melts and the edges are golden brown, 10-12 minutes. (For 4 servings, return to top and middle racks; swap rack positions halfway through baking.) Transfer the flatbreads to a cutting board and top with cilantro and the pickled onions (drained) to taste. Cut into pieces, divide among plates and serve.

Recipe Tips

For extra char, broil the flatbreads for the last minute of baking.

If you prefer a milder flavor, remove the seeds from the poblano pepper before slicing.

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

FAQ

Can I use a different type of cheese?

Yes, you can substitute the mozzarella and Monterey Jack with provolone, cheddar or a dairy-free alternative. The flavor will vary, but the flatbreads will still be delicious.

Can I make these flatbreads gluten-free?

Absolutely! Use gluten-free flatbreads or pizza crusts. Check that your BBQ sauce is also gluten-free.

How do I store leftovers?

Store leftover flatbreads in an airtight container in the refrigerator for up to 3 days. Reheat in a toaster oven or conventional oven at 350°F until warmed through.
