Another meaty, firm-fleshed fish, such as halibut, can be used in place of the swordfish.
The swordfish can be baked in parchment paper instead of foil. For each piece of fish, fold a piece of parchment paper in half and trim into a half-heart shape large enough to hold a piece of fish. Open heart, place fish on one side of heart. To seal food inside, fold edges in overlapping pleats and twist end shut. En papillote is the French expression for this cooking method.
The pineapple salsa also goes nicely with grilled chicken or pork.
