Made this with chicken for dinner last night. It was VERY good. The herbs give it a citrusy taste, even though there's no actual citrus in it. Now I just have to write it down so I don't forget it!
white wine vinegar
fresh pineapple sage leaves
fresh lemon balm leaves
fresh oregano leaves
dried minced onion (could have used fresh, I was being lazy).
Whirred in the blender until the herbs are well chopped. Pour over chicken, marinate 2 - 3 hours.
Next time I'm going to try adding a touch of dijon mustard, I think...
