Combine ½ cup soy sauce, sriracha and chicken in a bowl or ziplock food storage bag and marinate for 30 minutes.
Meanwhile, in a small bowl, combine peanut butter, grated ginger, minced garlic, garlic chili sauce, 3 Tablespoons soy sauce, rice vinegar, and warm water, and whisk until smooth and blended. Add more water as needed to thin the sauce to desired consistency. Set aside.
When the chicken has finished marinating, heat oil in a medium cast iron skillet over medium-high heat. Cook chicken until browned and cooked through, turning once, about 10 minutes. Chicken is done when an instant read thermometer reads 165F. Let the chicken rest for 10 minutes and then slice.
To assemble the vermicelli noodle bowls, dividing evenly between four bowls, in each bowl arrange noodles, lettuce, carrots, cucumbers, jalapenos. Add sliced chicken, cilantro and, if desired, lemon slices and fresh mint.
Serve with the peanut sauce and peanuts.
