Number Of Ingredients 10

1 bunch lemon thyme or regular thyme
1 1/2 pounds hake fillets
1 pinches Fine sea salt and black pepper
3 bell peppers, preferably 1 red, 1 orange and 1 yellow, thinly sliced
4 1/2 tablespoons extra-virgin olive oil, plus more for drizzling
1/4 cup pitted, sliced black or green olives, or a combination
1 teaspoon sherry vinegar, plus more to taste
1 garlic clove, grated
1 cup loosely packed Italian parsley leaves, chopped
6 potatoes yukon gold

Steps:

Heat your oven to 400 degrees. Finely chop 1 tablespoon of thyme.
Season the fish fillets on both sides with kosher salt, freshly ground black pepper, and thyme you just chopped. Set the seasoned fish aside.
Slice your bell peppers and spread them on a rimmed sheet pan, seasoning them with 1-2 tablespoons of extra virgin olive oil, kosher salt, and freshly ground black pepper. Place the remaining thyme (sprigs, not chopped) on top of the pepper slices. Roast for 15-20 minutes, tossing the peppers occasionally, until they're softened and just starting to brown.
Cut the potatoes into 1/2 inch dice and season them with olive oil, kosher salt, and freshly ground black pepper. Lay the on a baking sheet lined with aluminum foil. Place them in the oven at the same time as the bell peppers. They should be ready to serve at the same time as the fish.
Increase your oven temperature to 500 degrees. Move softened peppers to the sides of the sheet pan, and lay the fish fillets out on the empty space in the middle of the pan. Drizzle the fish with olive oil. Scatter the green and black olives across the sheet pan. Roast until the fish turns opaque and is just cooked, 6 to 10 minutes.
