Saute the onion and garlic together over low heat, in a medium saucepan, being careful not to burn the garlic. Add the sugar and let it dissolve until almost caramelized. Stir in the pineapple, watermelon, and vinegar and allow to cook until the fruit is coated with the liquid in the pan, about 2 to 3 minutes. Season with salt, to taste, and serve with chopped mint and goat cheese.
