Cook your base: Prepare rice or cauliflower rice according to package directions. Keep warm.
Whisk the sauce: In a small bowl, combine soy sauce, water, rice vinegar, maple syrup, sesame oil, cornstarch, and red pepper flakes.
Whisk until smooth. Set aside.
Sauté the aromatics: Heat a large nonstick skillet over medium heat. Lightly mist with cooking spray or add 1 teaspoon neutral oil if needed.
Add the onion and cook 2–3 minutes until softened. Stir in garlic and ginger; cook 30 seconds until fragrant.
Brown the turkey: Add ground turkey. Break it up with a spatula and cook 5–7 minutes, until no longer pink and lightly browned.
Season with a pinch of salt and pepper if desired.
Add veggies: Stir in broccoli, bell pepper, and carrot. Cook 3–4 minutes until crisp-tender. If the pan looks dry, add a splash of water to steam the veggies.
Glaze with teriyaki: Give the sauce a quick stir (the cornstarch settles), then pour it into the skillet.
Toss everything to coat. Simmer 1–2 minutes until the sauce thickens and glazes the turkey and vegetables.
Assemble bowls: Divide rice or cauliflower rice into bowls. Top with the teriyaki turkey mixture.
Garnish with green onions and sesame seeds. Add lime wedges, cucumbers, or edamame if you like.
Taste and adjust: For more sweetness, add a drizzle of honey. For more brightness, squeeze lime or add a splash of rice vinegar.
