Step 1: Grab a bowl and add your red onion, lemon juice, and 1 tablespoon oil in a bowl. Season this with kosher salt and pepper and leave this to the side.
Step 2: Grab a skillet and add your remaining tablespoon of oil over medium heat. Season chicken with salt and pepper. Cook your chicken until it's golden brown and cooked through, 6 to 8 minutes per side. Transfer this onto a cutting board and let it rest for 5 minutes. Slice up your chicken.
Step 3: Add your pomegranate seeds, cucumbers and parsley to your onion mixture and stir. Spread hummus onto your flatbreads and top it with your chicken, onion mixture and feta.
