1. Bring broth to a boil in a 2-quart saucepan; stir in brown rice. Cover, reduce heat, and simmer 40 minutes or until rice is tender. Remove from heat; let stand, covered, 5 minutes. Drain well.
2. Preheat oven to 350°. Bake pine nuts in a jelly-roll pan 6 to 8 minutes or until lightly toasted and fragrant, stirring after 4 minutes.
3. Stir together hot cooked rice, roasted red bell peppers, and next 3 ingredients in a large bowl.
4. Whisk together lemon zest and next 5 ingredients in a small bowl. Add olive oil in a slow, steady stream, whisking constantly until blended. Drizzle over rice mixture; toss to coat. Sprinkle with toasted pine nuts and crumbled feta cheese. Serve immediately, or cover and chill up to 24 hours. If chilled, let stand at room temperature 15 minutes before serving.
