Pound Chicken flat with a meat tenderizer or slice chicken breasts in half to make them thinner. In medium bowl or ziplock bag, combine the chicken, olive oil, oregano, garlic and a sprinkle of salt and pepper. Heat a large heavy duty pan to medium-heat and grill chicken 5-6 minutes per side until tender and cooked through. Remove from pan, cool for 5 minutes then slice or chop.
Combine all the ingredients for the dressing in a mason jar and shake to combine. alternately, whisk i s a small bowl.
In a large bowl, combine all the chopped ingredients for the salad. Top with chopped chicken a drizzle with generously with dressing. Serve immediately.
Notes
I like to use fresh grilled chicken that I grill on the stovetop or outdoor grill but any pre-cooked chicken you have on hand will work just as good.
