This is a main course built for summer: substantial but light, with a refreshing salad beneath. If you'd prefer skinless fillets, by all means use them, but be aware that the delicate edges may break up a bit. Prep and Cook Time: about 1 hour. Notes: Wash the arugula the night before and chill, wrapped in a kitchen towel and stored in a resealable plastic bag. Make the toasts (grilled instead of broiled, if you like) a day ahead and keep in an airtight container. The vinaigrette can be made up to a week ahead and kept in the refrigerator. The fish can be seared (2 to 3 minutes per side in a hot pan) shortly before dinner, then put in a 350° oven for about 8 minutes to finish cooking (an easy way to get all 8 servings ready at once).
8 slices (1 in. thick) crusty bread, such as pugliese, cut on a diagonal
About 2/3 cup extra-virgin olive oil, divided
3/4 teaspoon sea salt or coarse kosher salt, plus more for sprinkling on bread and fish
1/4 teaspoon freshly ground black pepper, plus more for sprinkling on bread and fish
2 cloves peeled garlic, cut in half
1 can (15 oz.) cannellini or other white beans, rinsed and drained in a colander
8 red snapper or Pacific cod fillets with skin (6 to 8 oz. each), rinsed and dried
About 8 cups arugula leaves (about 1/3 lb.), washed and dried
1 pint mixed red and yellow cherry tomatoes (about 3 cups), rinsed and halved
About 1/2 cup store-bought black-olive tapenade
8 sprigs flat-leaf parsley
How to Make It
Preheat broiler. Put bread slices on a large baking sheet, brush both sides with olive oil (about 6 tbsp.), and sprinkle with salt and pepper to taste. Broil bread on both sides until golden and crunchy, about 2 minutes per side. When toasts are cool enough to handle, rub each on one side with garlic halves. Lower heat to 325°.
Zest 1 lemon (to yield 1 tsp. zest) and squeeze half of it (to yield 2 tsp. juice). Cut other lemon into wedges. In a large mixing bowl, whisk together 3/4 tsp. salt, 1/4 tsp. pepper, lemon zest, lemon juice, and 2 tbsp. olive oil. Add beans and toss gently to mix. Set aside.
With a very sharp knife, make shallow slashes about 1 in. apart in skin of snapper fillets. Season fillets with salt and pepper. Heat 1 tbsp. olive oil in a large nonstick frying pan over medium-high heat. Add 4 fillets skin side down, reduce heat to medium, and cook 5 to 6 minutes, pressing often with spatula to keep them as flat as possible; turn over and cook another 2 minutes. Transfer to a baking sheet and reserve pan juices in a bowl. Wipe pan clean with paper towels and cook remaining fillets the same way, reserving pan juices and transferring to baking sheet. Put fish in oven and cook until done, about 8 minutes (cut to check).
Add arugula and tomatoes to beans and toss gently but thoroughly. Divide salad among 8 plates, arranging in center.
Set toasts, garlicky side up, on salads and top toasts with snapper fillets, skin side up. Drizzle each fillet with a bit of pan juice, then top with about 1 tbsp. tapenade and a parsley sprig, and a drizzle of olive oil. Garnish each plate with a lemon wedge. Drizzle some olive oil over each.
