Heat a pan over medium-high heat. Add 1 tablespoon of peanut oil along with the ground chicken. Sprinkle just a dash of salt and pepper. If the chicken releases a lot of water as it cooks, make sure to drain and keep cooking until golden. Remove the chicken from the pan and transfer to a bowl.
To the same pan, add another tablespoon of peanut oil along with the mushrooms and water chestnuts. Saute for 2 to 3 minutes or until golden.
Add the ginger and garlic and saute for another minute.
Add back the chicken to the pan. Then add the soy sauce, hoisin, rice vinegar, and sriracha. Mix all together.
Toss in the cilantro and green onions and mix again. Taste and adjust anything to your liking. Transfer to a bowl and allow to cool slightly for a few minutes.
Optional: Add vegetable oil to a pan and get it hot. Separate the rice noodles and break into smaller sections. Test if the oil is hot enough by adding one rice noodle. It will puff up in a matter of sections. Have a utensil ready to remove them from the oil and transfer to a bowl. If it is hot enough, drop the rest in and after a few seconds, they will puff up and remove from the oil.
Grab your romaine or butter lettuce. Add some of the chicken filling and top with some crispy noodles. Enjoy!
