Thai Sunbutter (Peanut) Sauce

4 teaspoons vegetable oil,
1/2 cup minced red onion
2 tablespoons minced garlic
1/2 teaspoon crushed red pepper flakes
2 tablespoons sugar
2 tablespoons vinegar
1/3 cup Sunbutter (peanut butter if you can have it)
1 cup of water
chopped cilantro - optional

In a blender, combine vegetable oil, onion, garlic and crushed red pepper flakes; blend for 1 minute.
Empty the mixture into a saucepan and place over low heat until the mixture starts releasing aroma. Add sunbutter and mix well over low heat. Add water and let it simmer for 10 minutes or until thickened. Stir in vinegar and sugar; continue to simmer for another 1-2 minutes. Sprinkle fresh cilantro on top just before serving.

Use to dip chicken or steak kabobs in.
