Preheat your oven to 400°F (200°C). Gather your ingredients and baking sheet.

Season the chicken breasts generously with salt, pepper, and optional garlic powder or Italian seasoning.

In a skillet over medium heat, add olive oil and heat for a minute. Cook the seasoned chicken breasts, about 6-7 minutes on each side.

Remove the chicken from the skillet and let it rest for 5 minutes before slicing into thin strips.

Spread fresh basil pesto evenly over each flatbread on a clean baking sheet.

Arrange the sliced chicken over the pesto, then add shredded mozzarella cheese, halved cherry tomatoes, and grated Parmesan.

Bake in the preheated oven for 10-12 minutes until the cheese melts and edges are golden brown.

For extra crispiness, broil for an additional 1-2 minutes, watching closely to prevent burning.

Allow the flatbreads to cool slightly, slice into pieces, and garnish with fresh basil leaves before serving.
