Begin by preheating your oven to 400°F (200°C) to ensure it’s ready for baking.
Line a baking sheet with parchment paper or lightly grease it, then place the flatbreads flat on the sheet. Use a pastry brush to lightly coat the top of each flatbread with olive oil.
In a medium mixing bowl, combine the shredded chicken with the pesto sauce. Add the garlic powder, then season with salt and pepper to taste. Stir thoroughly until the chicken is well-coated.
Spread the pesto chicken mixture evenly across each flatbread, covering all the way to the edges.
Sprinkle the shredded mozzarella cheese over the pesto chicken on both flatbreads.
Scatter the chopped sun-dried tomatoes and crumbled feta cheese on top of the mozzarella layer.
Place the baking sheet in the preheated oven and bake for 12-15 minutes until the cheese is melted and bubbly.
Remove the flatbreads from the oven and let them sit for a couple of minutes to cool slightly before slicing.
Garnish the flatbreads with freshly chopped basil leaves before serving. Slice into wedges and serve warm.
Notes
Serve with extra pesto for dipping and fresh basil for garnish.
