Add the onion and coconut oil to a pan and fry gently until translucent.

Add the ginger, and fry for about 1 minute.

Add the peppers, cucumber, and pineapple. Cook until just softened.

Add the tomatoes, bring to the boil and simmer gently for about ten minutes. 

Add the vinegar to taste. If you do make it a little too sharp, you can add more pineapple, or event a little sugar to balance it. 

Serve as a side, or as a dish all of it's own.
