This is really simple, but surprisingly good. The chicken is somewhat garlicky and tangy because of the lime juice, but it is not too strong-tasting. It goes great with mashed potatoes and corn muffins.
In a medium bowl, whisk together the lime juice, olive oil, and garlic.
Season with salt and pepper generously, and add chicken, making sure it is well-coated with the marinade. Marinate chicken, covered in fridge for at least 3 hours and preferably overnight. Preheat oven to 400 degrees F.
Remove chicken from marinade and discard marinade. Arrange chicken breasts in a shallow baking pan.
Season with salt and pepper and roast for 25-30 minutes or until chicken is cooked through and the juices run clear when you prick it with a fork.
