This easy dish comes together quickly and is cooked all on one baking sheet. Putting the pan in the oven while it preheats makes it hot enough to lightly sear the chicken and vegetables, adding texture and flavor and also reducing the cook time. Chicken thighs emerge from the oven succulent and coated in the savory sauce (with less salt because of the low-sodium soy sauce) and fragrant from the garlic, ginger and scallions. We recommend serving this with brown rice or whole-wheat noodles.
