Make the sauce. In a small saucepan, heat oil. Add onion and garlic. Stir until translucent. Stir in the rest of the ingredients. If the mixure is not already bubbling, increase heat. As soon as it bubbles, reduce to a simmer. Let it reduce and thicken (5-10 minutes), stirring occasionally. Taste and adjust seasonings to your liking - sweetness, spice level, salt, etc.
