1. Preheat oven to 425°.
2. Place shallots and beans on a jelly-roll pan coated with cooking spray. Drizzle bean mixture with 1 1/2 teaspoons oil, and sprinkle with salt and sugar; toss to coat. Bake at 425° for 20 minutes or until beans are crisp-tender. Transfer mixture to a serving bowl.
3. Place bread in a food processor; pulse 10 times or until coarse crumbs measure 3/4 cup. Heat remaining 1 1/2 teaspoons oil in a small skillet over medium heat. Add breadcrumbs to hot oil; cook 5 minutes or until golden, stirring frequently. Remove from heat; stir in cheese, walnuts, and lemon rind, if desired. Add breadcrumb mixture to bean mixture; toss well.
