How to Make It
Soak rice noodles according to package directions.
Meanwhile, heat oil in a grill pan or cast-iron skillet over medium-high. Season chicken with salt and pepper and cook, flipping once, until charred and cooked through, 4 to 5 minutes per side. Transfer to a cutting board and let rest for 5 minutes. Thinly slice.
Whisk peanut butter, coconut milk, lime juice, soy sauce, and sriracha in a small bowl.
Serve chicken and noodles with lettuce, cucumber, and peanut sauce, alongside scallions, basil, and peanuts for topping.
