Fish:

2 filets whitefish (tilapia is best)
1/4 tsp. oregano
1/8 tsp. paprika
pinch cayenne

Mix the spices and sprinkle onto only one side of the fish. Squeeze 1 lime over fish, and grill over medium coals until fish is flakey. Garnish with mango salsa.

Salsa:

1 peeled mango
juice of 1 lime
1 garlic clove
1 green jalapeno, chopped (and de-seeded if you want it less spicy)

Throw all into a food processor and blend away. Blend less if you want it chunkier.
