The original recipe is from bon appetit and is online. Here's how I made it:
1 head boston or butter lettuce, leaves removed, washed, and left whole
1/2 cup Asian sweet chili sauce
1 lb skinless, boneless chicken breasts, cut into about 1/2" cubes
3 scallions, minced
3 tablespoons reduced sodium soy sauce
1 teaspoon corn starch
2 tablespoons sesame oil
4 medium shiitake mushrooms, stemmed and minced
3 cloves garlic, minced
1 tablespoon fresh ginger, peeled and minced
1/4 cup unsalted roasted cashews, chopped
Whisk the soy sauce, scallions, and corn starch in a medium bowl. Stir the chicken in and marinate for 10 minutes at room temperature, stirring occasionally. Heat oil in a large nonstick skillet. Add mushrooms and stir-fry for about 15 seconds. Add garlic and ginger and stir-fry for 10 seconds. Add the chicken mixture and cook, stirring often until golden brown and cooked through, 6-7 minutes. Place a spoonful of the chicken mixture in each lettuce leaf. You'll probably need 12-16 lettuce leaves. Garnish with cashews. Drizzle sweet chili sauce over the chicken and roll leaves around the filling to eat.
Note: don't be dumb like me and spoon the hot chicken mixture into a lettuce leaf with a tear while holding the lettuce leaf in your hand. Wow, that burned! Sometimes I'm amazed at the things I do...
