Ingredients

Scale

  • 2 flatbreads (naan or pre-baked pizza crusts work great)

  • 2 tablespoons olive oil, divided

  • 2 large yellow onions, thinly sliced

  • 1 teaspoon balsamic vinegar

  • 1 zucchini, sliced

  • 1 red bell pepper, sliced

  • 1/2 cup shredded mozzarella cheese

  • 1/4 cup crumbled goat cheese or feta (optional)

  • 1 teaspoon fresh thyme (or 1/2 tsp dried)

  • Salt and black pepper, to taste

  • Optional: fresh arugula or basil for topping

Instructions

  1. Caramelize the Onions: In a skillet over medium heat, add 1 tablespoon olive oil and the sliced onions. Cook slowly, stirring occasionally, for 20–25 minutes until golden and soft. Stir in balsamic vinegar during the last 5 minutes.

  2. Grill the Veggies: Toss zucchini and bell pepper with remaining olive oil, salt, and pepper. Grill or roast at 400°F for 10–15 minutes until tender and slightly charred.

  3. Assemble the Flatbreads: Preheat oven to 425°F (or keep grill on). Place flatbreads on a baking sheet or grill-safe surface. Spread caramelized onions evenly over each, then top with grilled veggies, mozzarella, and crumbled goat cheese. Sprinkle with thyme.

  4. Bake or Grill: Cook for 8–10 minutes, or until cheese is melted and edges are crisp.

  5. Serve: Top with fresh arugula or basil if using. Slice and serve warm.

 

Notes

  • Feel free to use other veggies like mushrooms, eggplant, or cherry tomatoes.

  • Add a drizzle of balsamic glaze for extra flavor.

  • To make it vegan, use plant-based cheese or skip the cheese altogether.
