Fast cashew chicken with chicken thighs, toasted cashews, water chestnuts, celery, bell pepper, green onions, garlic, and ginger in a glossy soy–rice vinegar–honey sauce. Serve with rice; about 20 minutes.

In a small bowl, whisk all sauce ingredients until combined.
Preheat the oven to 175°C (350°F). Spread cashews on a baking sheet and bake 5–8 minutes, or toast in a dry pan until lightly golden; set aside.
Season chicken with salt and pepper. Heat oil in a wok or large frying pan, add chicken, and sear 6–8 minutes, turning often, until evenly browned and cooked through.
Add a little more oil if the pan is dry. When hot, add green onion and stir-fry about 1 minute until lightly charred. Add garlic and ginger; stir-fry 30 seconds.
Add celery and bell pepper; stir-fry vigorously about 30 seconds until the peppers start to soften. Return the chicken, add water chestnuts, and stir-fry 30 seconds to 1 minute. Pour in the sauce, bring to a boil, and stir-fry about 25 seconds more until thickened and glossy.
Fold in the cashews and serve with rice.
