Pork: Thinly slice pork tenderloin. Stir together marinade and hoisin sauce in a medium bowl. Combine pork and marinade mixture. Stir to evenly coat, cover and refrigerate for at least 1 hour.
When ready to prepare the meat, preheat oil in a large skillet over medium high heat. Remove ⅓ of pork from marinade with tongs and quickly saute for 1-2 minutes. When done, remove to a plate and keep warm. Repeat with remaining pork.
Cilantro-Lime Rice: Prepare rice according to package directions. After rice is cooked, stir in cilantro, lime juice and salt to taste.
Wraps: Evenly divide pork and rice among lettuce leaves. Top with sweet chili sauce, if desired.
