A simple marinade of lime juice, zest and spices like cumin and chili powder creates quick flavor in this juicy cilantro-lime chicken. Slice the chicken and enjoy over salad greens, in a taco or with rice.
Combine oil, lime zest, lime juice, cumin, coriander, chili powder and salt in a large sealable plastic bag. Add chicken; seal the bag and massage to coat the chicken. Let stand at room temperature for 15 minutes.
Heat a large nonstick skillet over medium-high heat. Remove the chicken from the marinade; discard the marinade. Add the chicken to the pan in an even layer; cook, undisturbed, until browned on the bottom, 5 to 6 minutes. Flip and cook until a thermometer inserted into the thickest part registers 165°F, 5 to 6 minutes. Transfer to a platter. Do not wipe the pan clean.
Add scallions to the pan; cook, stirring constantly, until blistered and tender, about 2 minutes. Scatter the scallions around the chicken. Drizzle with the juices from the pan and sprinkle with cilantro. Serve with lime wedges, if desired.
