Heat grill to medium heat. Drizzle red onion, jalapeno and garlic cloves with olive oil. Wrap each garlic clove in aluminum foil large enough to prevent falling through the cracks.
Place onion, jalapeno, and garlic onto the grill. Sear for 10 minutes, turning every 2 minutes, or until onion is soft and caramelized, jalapeno is nicely charred and garlic cloves are soft.
Remove from grill and allow to cool. Skins from the jalapeno and garlic should easily peel off.
Add onion, jalapeno, and garlic to blender or food processor, pulse several times until a paste forms.
Add remaining ingredients and blend until smooth, but slightly thick.
Use immediately or refrigerate for up to one week.

Notes
If you do not want to grill, you can also roast in the oven on 350 degrees for 20 minutes, or until soft.
