Fold En Papillote

Fold a 14×12“ piece of parchment paper in half. (The technique also works for grilling; just substitute aluminum foil.) Using kitchen shears, cut the parchment into a heart shape.

Arrange vegetables and herbs on one side of the paper. Top with fish. Add olive oil or butter and a splash of wine and/or broth to keep the fish moist and create a sauce. Season with salt and pepper. Brush the edges of the paper with beaten egg white for a tighter seal, if desired.

Working from one end, begin tightly folding the open edge of the paper.

Continue folding the paper's open edge to form a seal. Transfer the packet to a rimmed baking sheet and bake. (If using foil, place directly on the grill.)
