Instructions

  1. Preheat your oven to 450°F and adjust a rack to the upper position. Wash and dry all produce. Halve the grape tomatoes lengthwise. Thinly slice the fresh mozzarella. Roughly chop the walnuts.
  2. Place the flatbreads on a baking sheet. Spread the pesto evenly over the top of each flatbread.
  3. Arrange the sliced mozzarella and halved tomatoes on top of the pesto. Bake until the cheese is melted and bubbly and the tomatoes have softened, about 8-10 minutes.
  4. While the flatbreads bake, make the dressing: In a medium bowl, whisk together 1 tablespoon of balsamic vinegar (you’ll have extra) and a generous drizzle of olive oil.
  5. Add the arugula to the bowl with the dressing and toss to coat. Season with salt and pepper to taste.
  6. Remove the flatbreads from the oven. Top with the dressed arugula and sprinkle with the chopped walnuts. Tear the basil leaves and scatter them over the top. Slice and serve immediately.

Recipe Tips

For extra crispiness, bake the flatbreads directly on the oven rack for the last minute.

If your flatbreads are thick, you can pre-bake them for 2 minutes before adding toppings.

Toast the walnuts in a dry skillet over medium heat for 2-3 minutes to enhance their flavor.

FAQ

Can I use a different type of flatbread?

Yes, any pre-made flatbread, naan or even pita bread will work. Adjust baking time as needed.

What can I substitute for pesto?

You can use sun-dried tomato pesto, basil pesto or even a simple garlic-herb oil.

How do I store leftovers?

Store leftover flatbreads in an airtight container in the refrigerator for up to 2 days. Reheat in the oven or toaster oven to restore crispness.
