Preheat your grill to 400°F.

If the chicken breasts are thick, butterfly them and gently pound to about 1/4 inch thickness.

In a Ziploc bag, combine olive oil, lime juice, lime zest, sliced garlic, chopped cilantro, salt, and pepper. Add the chicken and marinate for 20-25 minutes.

While the chicken marinates, prepare the pineapple salsa: dice grilled pineapple, finely dice shallots and jalapeno, and add to a bowl with red bell pepper, corn, lime juice, and a pinch of salt. Mix gently.

Place a sheet of foil on the preheated grill. Place the chicken on the foil and grill for about 3 minutes on each side until cooked through.

Remove the chicken from the grill, transfer to a platter, and top with the pineapple salsa. Garnish with optional crushed peanuts and sliced scallions if desired.

Serve immediately with lime wedges.
