Cook rice according to package directions. Heat vinegar, sherry, sugar, and lemon rind in small saucepan over medium heat until sugar is melted, about 1 minute. Drizzle vinegar mixture over rice and toss.
While rice is cooking, cook pine nuts in sesame oil in small skillet over medium heat until toasted, about 2 minutes; remove from skillet. Add snow peas, gingerroot, and water to skillet; cook, covered, over medium heat until snow peas are crisp-tender, 2 to 3 minutes.
Stir pine nuts, snow peas, gingerroot, beans, cucumber, orange and green onions into rice. Season to taste with salt and pepper. Serve warm, or refrigerate and serve chilled; spoon about 1/4 cup packed rice mixture onto each lettuce leaf and roll up.
