Spread half of the basil pesto evenly over each flatbread, leaving a little edge around the perimeter.
Evenly distribute the shredded chicken on top of the pesto on both flatbreads.
Sprinkle the shredded mozzarella cheese over the chicken, ensuring it covers thoroughly.
Add the chopped sun-dried tomatoes and toasted pine nuts on top of the cheese.
Scatter the baby spinach over everything. Drizzle with olive oil and season with salt and pepper to taste.
Place the flatbreads on a baking sheet and bake in the preheated oven for about 10-12 minutes or until the cheese is melted and bubbly and the edges are golden brown.
Once done, remove from the oven and let it cool for a minute. Garnish with fresh basil leaves before cutting into slices.
Notes
Serve the slices on a wooden board or a colorful platter, with a small bowl of extra pesto on the side for dipping.
