Make the sauce by combining the soy sauce, rice vinegar, honey, water, cornstarch, ginger, garlic, and orange zest in a small bowl and whisk until thoroughly combined. Set aside to allow flavors to mingle.
Cook the chicken by heating the olive oil in a large skillet or wok over medium heat. Add the ground chicken and cook, making sure to break it into pieces, for 4-5 minutes.
Add the chopped carrots and bell pepper to the skillet. Continue to cook, stirring occasionally, until chicken is browned and cooked through, about 2-3 minutes.
Once the chicken is cooked, add the cashews and red pepper flakes to the skillet. Cook, stirring, for 1 minute.
Add the well-whisked sauce and cook for 1-2 minutes until most of the liquid has been absorbed.
To serve, place the chicken and vegetable mixture in a serving bowl and top with green onions. Serve immediately with lettuce wraps and sriracha, if desired. Enjoy!
