* Fish should be Orange Roughy, Haddock, or Mackerel, cut into 1/2" ** If fresh Cilantro is not available, use 1 t dried cilantro leaves. *** If fresh oregano is not available, use 1/4 t dried oregano leaves. **** Olives should have pimiento stuffing. ***** Jalepeno Chiles should be seeded and chopped.
Heat 3/4-inch of water to boiling in 10-inch skillet; carefully place fish in water. Heat to boiling; reduce heat. Simmer, uncovered, just until fish is opaque, about 30 seconds (DO NOT overcook or fish will fall apart); drain carefully. Mix remaining ingredients except tomato and avocado in a glass or plastic dish. Stir in fish carefully. Cover and refrigerate 2 day, carefully stirring occasionally. Just before serving, gently stir in tomato and avocado; drain. Serve fish mixture on saltine crackers or tortilla chips, if desired.
