2 heads butter lettuce, leaves separated
MAKE THE SAUCE: In a bowl, combine the chili sauce, hoisin, soy sauce, Sriracha, vegetable oil, sesame oil, vinegar, garlic, and ginger.
MAKE THE FILLING: In a bowl, mix 2 tablespoons of the sauce into the ground chicken.
In a large skillet, heat 2 tablespoons of the vegetable oil over medium-high heat. When shimmering-hot, add the chicken and cook, breaking up the meat with a wooden spoon, until browned, 5 to 6 minutes. Transfer the meat to a plate and set aside.
Add the remaining 1 tablespoon oil to the skillet, then add the scallion whites, garlic, and ginger and cook, stirring, for 1 minute.
Add the mushrooms and cook, stirring, until they release their liquid, 3 to 4 minutes. Return the chicken to the pan, then add the water chestnuts, bell pepper, and the rest of the sauce and cook, stirring, until cooked through and the liquid has reduced and thickened slightly, 3 to 4 minutes. Stir in the scallion greens.
Transfer the mixture to a bowl and set out with the lettuce leaves.

"Vegetables are perishable, so we don't have any indication of what they looked like 500 years ago," says James Nienhuis, a professor in the Department of Horticulture at the University of Wisconsin.
