Prepare: If necessary, defrost the Meati cutlets overnight in the fridge for best results. Wash, chop, and slice the lettuce, cucumber, carrot, peppers, green onions, and cilantro. Mince the garlic and ginger for the sauce.
Mix: In a small bowl, mix together gochujang, soy sauce, sesame oil, maple syrup, minced garlic, and sesame seeds until smooth. If the sauce is too thick, thin it out with a tablespoon of water.
Boil: Fill a medium-sized saucepan with water and bring it to a rolling boil. Toss in the noodles and cook them per the packaging guidelines. Once done, drain the noodles and rinse them under cold water until they're completely cool. Set aside.
Cook: While the noodles are cooking, coat the Meati cutlets with some of the sauce you just made. Place the chicken in the hot pan (or in the air fryer or oven, see notes). Cook until golden on the underside, which should take about 3 minutes. Flip the Meati chicken and cook for another 2 minutes or until fully cooked. Move the chicken to a cutting board, let it rest for about 5 minutes, and then cut it into slices or bite-sized chunks.
Assemble: Divide the cooked noodles, lettuce, cucumber slices, grated carrots, peppers, sliced green onions, fresh cilantro, pistachios, and your cooked, sliced Meati into individual bowls. Drizzle each bowl with a generous amount of the remaining sauce. Serve lime wedges on the side if you like a citrusy kick.
