In a a large skillet over medium-high heat, add ½ tablespoon olive oil. Sprinkle chicken evenly with ½ teaspoon salt. Add chicken to pan; sauté 6 minutes or until browned. Turn; sauté 4 minutes or until chicken is done.
Make the sauce:
Smash ¼ teaspoon salt, shallots, and garlic with mortar and pestle. If you don't have a mortar and pestle, use the back of a spoon to smash in a small mixing bowl. Mash together until you form a paste. Combine garlic mixture, sesame oil, soy sauce, sriracha sauce, lime zest and cilantro.
Top the Chicken:
Place 1-½ teaspoons cilantro sauce over each piece of chicken. Serve.
Notes
In grilling season, I would highly recommend grilling your chicken rather than sauteeing in the pan. The flavor from the grill would only add to this great sauce, which is the star of the party!
