Here a recipe I came up with years ago.

I've won a few recipe contests with it and variations thereof.
It's kind of a sweet-hot chimichurri and is dynamite on grilled shrimp, both as a marinade and a dipping sauce.

In a blender, I put a bunch of cilantro, stems and all...a bunch of green onions...a couple of jalapenos, a few garlic cloves...some salt...and a can of orange-pineapple juice concentrate. Puree until smooth.
If you don't want it sweet, squeeze a couple of limes or wine vinegar instead of the juice concentrate. You can substitute yellow onions for the scallions...habaneros for the jalapenos, etc. It's all good.
