In a bowl, mix soy sauce, honey (or brown sugar), olive oil, garlic, ginger, black pepper, and rice vinegar.

Set aside 2 tbsp of the marinade for later (for a finishing sauce).

Place chicken breasts in the marinade for 10-15 minutes (or up to overnight for deeper flavor).

Stovetop Method (Quick & Easy)

Heat a pan over medium-high heat and add a little oil.

Add chicken and cook for 4-5 minutes per side until browned and cooked through (internal temp 165°F).

Pour the reserved marinade into the pan and let it simmer for 1-2 minutes (add cornstarch mixed with a little water if you want it thicker).

Oven Method (Hands-Off Cooking)

Preheat oven to 400°F (200°C).

Place chicken in a baking dish, pour the marinade over, and bake for 18-20 minutes.

Broil for the last 2 minutes for a nice glaze.

Let chicken rest for 5 minutes, then slice.

Garnish with green onions and serve with rice, steamed veggies, or a side of stir-fried noodles.
