Prep Chicken: Place 2-4 skinless, boneless chicken breasts on plate and sprinkle both sides with a generous amount of kosher salt and ground black pepper.
Grill Chicken: Heat grill to medium heat (approximately 400℉). Place chicken on direct heat (direct flame) and cook for 4-5 minutes per side. Move chicken away from the direct heat, so that it is cooking on indirect heat (maintaining the same grill temp) and cook for an additional 5-10 minutes or until the internal temperature of the thickest part of the chicken reads 160℉ on your meat thermometer.
Rest + Cut: Remove from grill and let rest at least 5 minutes (the chicken will continue to cook during this time and the internal temp will continue to rise up to 10 additional degrees). Slice or cut into bite-sized pieces.
Make Salad: Add 4-6 cups romaine lettuce to a large bowl. Add bell pepper, cucumbers, kalamata olives, cherry tomatoes, 6 ounces feta cheese and diced red onions. Drizzle with 3-4 tablespoons Greek Vinaigrette and toss.
Add Chicken: Put the cut pieces of chicken in the salad and give it another mix.
Serve: Divide between 4-6 bowls and enjoy.
Notes
Storage: this salad stores best before everything is mixed together and especially before the dressing is added. If you want to make it the day before, store the chicken, greek salad, lettuce and dressing separately, so ingredients don't get mushy. Keep each in an airtight container in the fridge for 2-3 days.
Dairy-free: simply use a dairy-free feta cheese.
