Cook your base: Make brown rice or quinoa according to package directions. Fluff and set aside, covered, to keep warm.
Mix the sauce: In a small bowl, whisk soy sauce, pineapple juice, rice vinegar, honey, sesame oil, garlic, ginger, and red pepper flakes (if using).
In a separate small cup, stir cornstarch with cold water until smooth. Keep both nearby.
Prep the chicken: Pat chicken dry. Season with a pinch of salt and pepper.
This helps a quick sear and better flavor.
Sear the chicken: Heat oil in a large skillet over medium-high. Add chicken in a single layer. Cook 5–7 minutes, stirring a few times, until golden and just cooked through.
Transfer to a plate.
Cook the veggies: In the same pan, add broccoli and bell pepper with a splash of water. Stir-fry 3–4 minutes until crisp-tender. Add carrots and edamame and cook 1–2 minutes more.
Season lightly with salt and pepper.
Make it saucy: Return chicken to the pan. Pour in the teriyaki mixture and bring to a gentle simmer. Stir in the cornstarch slurry and cook 1–2 minutes, stirring, until the sauce thickens and turns glossy.
If it gets too thick, add 1–2 tablespoons water to loosen. Taste and adjust sweetness or salt.
Assemble the bowls: Spoon rice or quinoa into bowls. Top with chicken and veggies.
Scatter green onions and sesame seeds. Add any extras you like.
Serve: A squeeze of lime brightens everything. Enjoy warm.
