Grilled Red Mullet

Preheat oven to 350°F and prepare a grill for medium-high heat. Clean grate
well with a brush; oil grate. Toast pine nuts on a rimmed baking sheet, tossing
once, until golden brown, about 5 minutes. Let cool (that’s it for the oven).
Grill onions, turning occasionally, until skins are blackened and onions have
softened (some of the juices may ooze out), 15-20 minutes. Transfer to a
platter and let cool 10 minutes.

Split onions in half. Remove outer peel and discard. Separate onion layers into
individual petals. Transfer to a medium bowl and mix in pine nuts, capers,
raisins, and vinegar; season agrodolce with salt.

Season fish cavity and skin with salt; drizzle with 1/4 cup oil. Grill, resisting the
urge to turn, until skin is lightly charred and flesh is flaky and opaque down to the
bone, about 3 minutes for mullet and 8 minutes for snapper. Place a metal
spatula underneath fish, then lift and gently roll over onto the other side. Cook
until flesh is flaky and opaque, 3-8 minutes, depending on fish. If a small knife
slides easily through the thickest part of flesh, fish is done.

Transfer fish to a platter and spoon agrodolce over. Top with parsley and some red pepper flakes; drizzle with oil. Serve with lemon wedges.
