Cod and caper parcels with roasted cauliflower salad
POSITION racks in top and bottom thirds of oven. Preheat to 450F. Line a baking sheet with foil.
TOSS cauliflower florets and grapes with olive oil on prepared sheet. Roast in top third of oven until cauliflower is golden, about 30 min.
LAY 4 12 × 12-in. sheets of parchment on the counter. Arrange cod fillets, about 1 in. thick, in centre of squares. Sprinkle with salt. Divide butter, capers, shallots and sliced lemons over fillets. Fold parchment over fillets. Tightly double-fold around edges, making each packet a half-moon shape, so steam doesn’t escape. Arrange packets on another baking sheet.
