04Toss sliced fennel with 3 tablespoons oil, 1 teaspoon salt and 1/4 teaspoon pepper. Spread on the remaining baking sheet. Transfer fish and fennel to the oven; roast fennel, tossing occasionally, until golden and tender, about 15 minutes. Bake fish until it is just opaque, 15 to 20 minutes. Serve fish drizzled with more olive oil and squeeze fresh lime juice on top. Serve with fennel on top or alongside.
