In a medium bowl, add lime juice, oil, maple syrup, chili powder, cumin, garlic powder, salt and pepper. Whisk with a fork.
Add chicken to the bowl, cover and marinate for 30 minutes to 24 hours in the refrigerator. The longer you marinate, the deeper the flavor.
To pan fry: Preheat large ceramic non-stick skillet on medium heat and swirl a bit of oil to coat. Add chicken and cook for 5-6 minutes per side or until a meat thermometer inserted in the thickest part registers 165 F. Discard the marinade.
To grill: Preheat grill on medium-high heat (450-500 degrees F) and rub grates with oiled paper towel. Place chicken on the grill, close the lid and grill for 10-12 minutes turning once. Do not overcook.
To bake: Preheat oven to 450 degrees F. Rub bottom of large baking dish with oil and lay chicken breasts in a single layer. Bake uncovered for 25 minutes (thinner) to 35 minutes (2″+) or until 150 degrees F internal temperature. Discard marinade.
For all methods: Make sure you let chicken rest. Place cooked chicken onto a baking dish and cover with tin foil, silicone lid or paper towel. Let rest for 5 minutes. This step helps juices settle back into the meat.
