Husk the tomatillos and rinse. Lay on a baking sheet. Heat the broiler to high and roast for about 10 minutes, turning half way through. Remove from the oven and let cool.
In a food processor or blender add the tomatillos, onion, jalapeño, garlic, cilantro, and salt to taste.
Pulse until it reaches the desired consistency. Serve with chips.
