How to Make It
Preheat oven to 450º.
Combine oil, 1/4 teaspoon salt, 1/4 teaspoon pepper, beans, and potato in a medium bowl; toss to coat. Place potatoes on a jelly-roll pan lined with foil; bake at 450º for 10 minutes.
Reduce oven temperature to 425º. Add beans and tomatoes to pan; move potato mixture to one side of pan. Sprinkle fish with remaining 1/4 teaspoon salt and remaining 1/4 teaspoon pepper. Drizzle juice and Worcestershire sauce over fish. Add fish to pan. Bake at 425º for 18 minutes or until fish flakes easily when tested with a fork or until desired degree of doneness. Serve with lemon wedges, if desired.
