Heat the oil in a 3-quart non-corrosive saucepan over medium high heat.
Add onion and garlic and sauté until the onion is soft and golden, about 8 minutes.
Add the ginger and sesame seeds and sauté another minute.
Reduce heat to medium low and add the remaining ingredients.
Bring to a simmer and adjust heat to maintain a slow simmer and simmer gently for 20 minutes, stirring frequently.
