Cook your base: Prepare rice, quinoa, or cauliflower rice according to package directions. Keep warm. For the highest protein, consider quinoa or mix half rice with half cauliflower rice.
Prep the chicken: Remove skin and bones from the rotisserie chicken.
Shred or chop the meat into bite-size pieces. Set aside.
Make the sauce: In a small saucepan, whisk soy sauce, water, honey, rice vinegar, sesame oil, garlic, ginger, and sriracha (if using). Bring to a gentle simmer over medium heat, 2–3 minutes.
Thicken: Stir the cornstarch slurry, then slowly whisk it into the simmering sauce.
Cook 1–2 minutes until glossy and thick enough to coat a spoon. Reduce heat to low.
Sauté the veggies: Heat oil in a large skillet over medium-high heat. Add broccoli, bell pepper, snap peas, and carrots.
Stir-fry 4–6 minutes until crisp-tender. Season with a pinch of salt.
Add chicken: Add the shredded chicken to the skillet with the veggies. Pour in about half the teriyaki sauce and toss to coat.
Warm through for 2–3 minutes.
Assemble: Divide the hot rice or grains among bowls. Top with the chicken and veggie mixture. Spoon on extra teriyaki sauce to taste.
Finish: Garnish with green onions and sesame seeds.
Add more heat with chili flakes if you like.
