Step 1

In a medium sauté pan, heat oil over medium heat. Add the garlic, onion, and ginger. Sauté for 5 minutes, until soft and fragrant.

Step 2

Add the mashed bananas, tomato paste, and brown sugar. Mix well.

Step 3

Add the vinegar, water, and cayenne powder. Mix well and bring the mixture to a simmer. Reduce the heat to medium low and simmer for 10 minutes, until thickened slightly.

Step 4

Remove the pan from the heat and let the mixture cool slightly. Transfer the cooled mixture to the bowl of your food processor or blender. Blend until smooth.
