In a bowl, combine the chicken with the oil, sea salt, pepper, dried oregano, chili flakes, toss to get all the pieces coated.
Heat a skillet over medium heat, and add the chicken. Pan fry for about 4-5 minutes on each side, until the chicken is cooked through and tender. Transfer to a chopping board, and cover it with foil until you’re ready with the rest of the salad.
Meanwhile, prepare the dressing by whisking all the ingredients in a small glass bowl.
Slice the chicken and place it a large bowl together with the chopped kale, avocado, tomatoes, and parmesan.
When you are ready to serve stir in the dressing and mix well.
