Here's the recipe I used (from allrecipes):
Lemongrass Chicken Summer Rolls
2 pounds skinless, boneless chicken breast2 tablespoons minced fresh ginger root
2 tablespoons minced fresh jalapeno chile (I omitted)
1/2 cup peeled and thinly-julienned seedless cucumber
1/4 cup minced fresh Thai basil leaves
1/4 cup minced fresh mint leaves
1/4 cup minced fresh cilantro
1 1/2 tablespoons minced lemon grass
1/2 cup ground peanuts
1/4 cup fish sauce
3 tablespoons lime juice
2 teaspoons white sugar
1 tablespoon sesame oil
1 tablespoon peanut oil
Rice paper wrappers
Boil the chicken until no longer pink in the center (about 10 minutes depending on your pieces).
Remove, allow to cool, and shred into small pieces.
Toss together the chicken with the vegetables. Mix the fish sauce, lime juice, sugar, sesame and peanut oils, then add to chicken mixture and stir.
Dip one rice wrapper in a shallow pan of warm water to soften. Remove after a few seconds, drain a bit, and lay on flat surface. Place lettuce leaf on top, then some chicken (I drained the chicken a bit so that there wouldn't be so much sauce dripping out), then roll semi-tightly but be careful not to tear the wrapper. Set aside and repeat for the rest of the ingredients. Eat immediately, or wrap in plastic to seal in moisture and prevent drying out.
