You will need:

6 skinless, boneless chicken breasts, thinly butterflied

2/3 cup light rum

1/2 medium onion, peeled and minced

Juice of 1 lime

1/2 tsp salt or to taste

1/2 tsp pepper

1/2 tsp paprika (for color)

2 tbs vegetable oil, divided

Lime wedges, for garnish (optional)

Spicy salsa:

1 red onion, finely chopped

2 tomatoes, seeded and diced

1 cucumber, diced

1/4 cup yellow bell pepper, diced

1 red chile pepper, diced

1/4 tsp cayenne pepper (if you dare!)

4 tbsp chopped cilantro leaves

juice of 1 lime

Directions:  Mix onion, tomato, cucumber, cilantro, lime juice, and the diced peppers in a large bowl and refrigerate salsa until ready to use.

Rinse chicken breasts under cold water and pat dry with paper towels.

Prepare marinade. Place chicken breasts in a 1-gallon, resealable plastic bag. In a small bowl, stir together rum, onion, lime juice, salt, pepper, and 1 tbs vegetable oil. Pour marinade over chicken, push out air, seal the bag, and refrigerate for at least 4 hours.
Remove chicken from marinade and discard marinade. Use the remaining oil to glaze the grill and heat up the pan (I used cast iron) to medium-high. Carefully add each breast and cook 3-4 minutes per side or until juices run clear when pierced with a fork. Add 1 chicken breast to each plate and  top with spicy salsa.
