Start by seasoning 1 pound of your preferred meat (such as boneless chicken thighs, steak, pork, shrimp, or ground beef/turkey/pork/chicken) with oil, soy sauce, salt, and pepper. Cook the seasoned meat on the grill or sear it in a pan until done. Once cooked, cut the meat into small pieces. In a bowl, combine the cut meat with 1 cup of matchstick carrots, 1 cup of diced cucumber, 1/2 cup of green onion, 1/2 cup of chopped cilantro, and optional jalapeños and chile peppers for spice. Add 1/3 cup of Hoisin Sauce to the mixture. Mix all ingredients together thoroughly. Serve the mixture on butter lettuce or romaine leaves.
