Preparation
Preheat grill or broiler. Mix picante sauce, oil, and lime juice in a bowl. Add garlic, cumin, oregano, and salt; stir. Reserve 1 cup of marinade; set aside.
Pierce chicken on both sides with a fork. Place chicken in a resealable plastic bag. Pour marinade over chicken; squeeze air out of bag and seal tightly. Toss chicken to coat well. Refrigerate for about 5 minutes, drain.
Grill chicken over medium heat, turning and basting frequently with 1/2 reserved marinade for 20 minutes or until cooked through. Heat remaining marinade and serve along side chicken. Rice Pilaf makes a great partner.
