Preheat the oven to 450°F to 500°F. Mix the olive oil and lemon juice and brush it on a baking pan and both sides of the salmon. Place the salmon in the pan and sprinkle with salt and pepper. Cover the salmon with the bread crumbs, then sprinkle with the capers and drizzle with the butter. Bake until the fish is just cooked through, 5 to 7 minutes. Serve with sautéed spinach or Swiss chard or broccoli.
