Rinse fish in cool water and pat dry. Combine 2 teaspoons oil, 2
tablespoons lemon juice and 1 teaspoon ginger and coat both sides of fish.
(Refrigerate for up to an hour.) To prepare Pineapple Salsa, heat
remaining oil in a medium skillet. Add yellow pepper and onion and saute
until soft. about 4 minutes. Add crushed pineapple, raisins, cayenne and
remaining lemon juice and ginger; saute until pineapple is warm, about 4
minutes longer. (Salsa can be made ahead up to 24 hours; but bring to room
temperature before using.) Grill fish 4 to 5 inches from hot coals,
turning once, until fish is barely opaque in the center, and just begins to
flake when tested with a fork about 2 minutes per side for 3/4-inch thick
fish steaks. Divide spinach and romaine among six plates and place a
grilled fish steak on each. Top with pineapple salsa as a dressing. Yield:
6 servings.
