  • Preheat broiler to high.
  • Heat remaining ½ tablespoon of oil in a large oven safe skillet to medium high heat. Add chicken and cook for 5 to 7 minutes per side, until cooked through.
  • Top chicken with the remaining pesto, tomato slices and Parmesan.
  • Place under the broiler for 2 to 3 minutes, until the cheese is melted.
  • Season to taste with salt and pepper.

Instant Pot

  • First, set your Instant Pot to high saute. When your pot says HOT, add the oil and chicken. Cook for 3 minutes per side, until browned.
  • Remove the chicken from the pot. Place the trivet and one cup of water in the bottom of the pot. Arrange the chicken in a single layer and top with the remaining pesto.
  • Place the lid on your Instant Pot and set it to high manual pressure for 6 minutes.
  • When the time is up, allow the pressure to release naturally for 5 minutes and then do a quick release.
  • Carefully remove the lid and add the tomato and cheese. Return the lid to the pot and allow it to sit until the cheese melts, about 3 or 4 minutes.
  • Season with salt and pepper.
