In a 12 inch stainless steel skillet, heat the vegetable oil over medium heat. Add chicken and saute the onion until the onion is soft and translucent, about 3 minutes. Add the ginger and garlic and cook for another minute.
Stir in the light brown sugar, and lime juice. Season the sauce with salt and pepper and simmer the sauce for 5 minutes until the chicken is fully cooked.
Taste the sauce, and adjust seasonings if necessary. Garnish the curry with chopped fresh cilantro. Serve over warm white rice or with naan bread on the side.
