Heat 2 tsp peanut oil in a large skillet or wok over medium-high heat until shimmering.
Add the 1 lb chicken thighs (cut into bite-size pieces) and stir-fry for about 2 minutes to brown.
Add 1/4 cup honey-roasted peanuts, the chopped red bell pepper, minced garlic, and minced ginger; stir and cook 3–4 minutes until the chicken is cooked through and vegetables are tender-crisp.
While the chicken cooks, whisk together 1 tbsp soy sauce, 2 tsp rice vinegar, 1 tsp Sriracha, 1 tsp sesame oil, and 1 tsp cornstarch in a small bowl until smooth.
Pour the sauce and the sliced 1/4 cup green onions into the skillet; stir constantly until the sauce thickens and evenly coats the chicken, about 1–2 minutes.
Remove the skillet from heat and stir in 1 cup chopped fresh cilantro.
Serve the cilantro chicken over hot cooked rice with lime wedges on the side.
