Place the fish in a medium-sized freezer bag. Remove the excess air and seal.
Stir together the mango cubes, diced onions, diced jalapenos, cilantro, lime juice, and melted honey. Put the salsa in another medium freezer bag and seal. Staple the two bags together.
Cooking Instructions:
On the day of cooking, take the bags out of the freezer. In a skillet, grill the fish 3-4 minutes per side. Thaw the salsa.
Place a piece of the grilled fish and some of the mango salsa in a flour tortilla. If you want, you can top it with guacamole and/or hot sauce.
