Prep everything first. Dice chicken, chop veggies, and whisk the sauce ingredients in a bowl. Mise en place, people. It makes this quick dinner actually cook faster.
Heat 1 tablespoon oil in a large skillet over medium-high heat. Add the chicken, season with salt and pepper, and cook until lightly browned and just cooked through. Remove to a plate; you’ll thank yourself later for not overcooking it.
In the same pan, add the remaining oil. Sauté garlic and ginger for about 30 seconds until fragrant—don’t burn them, or your tongue will revolt.
Slide in broccoli and bell pepper. Stir-fry 2–3 minutes until they’re crisp-tender. If you like softer veggies, cook a minute longer.
Return the chicken to the pan. Give the sauce a quick stir, then pour it in. Bring to a simmer and cook 1–2 minutes to let everything mingle.
Stir in the cornstarch slurry to thicken the sauce. Add cashews and toss to coat. Taste and adjust salt or a splash more vinegar if you want it brighter.
Serve hot over rice or noodles. Quick, easy, and saucy—just how we like it.
