Sorry I don't have measurments for you, I just taste as I go.

Pineapple juice (about 1 cup)
Orange juice (about 1/2 cup)
Jalapino juice (about 1/3 cup)
Water (about 1 cup)
Salt and pepper to taste
1 med onion cut up
a handful of jalapino's
1/2 bunch calintro

Mix all in a ziplock bag and taste, adjust to your tastes, just try not to let it get to citrusy. Add skinless, boneless chicken breasts. Let sit in fridge for 4 hours, or even over night.

Grill on grill till done, then slice into strips.
