(Citrus marinated fish)
Always loved this stuff!

1 lb firm white fish
1 small onion
1 clove garlic
4 or 5 sprigs of cilantro
1 small hot chili
¾ cup lime juice (about 8 limes)
¼ teaspoon salt
Pepper to taste

Cut fish into ½ inch cubes. Mince the onion, garlic, and chili coarsely. Chop the cilantro very finely. Juice the limes; strain to remove the pulp and seeds. Shrimp can be substituted for the fish. Mix all of the ingredients and refrigerate tightly covered for at least 3 hours. Serve with corn tortillas, tortilla chips, or crackers.
