BBQ Grilled Tomatillo Salsa

The lovely charred flavour that cooking on the BBQ adds, enhances the fresh citrusy flavour of the tomatillos.  This salsa is great on flat bread with melted cheese, burritos, pulled chicken enchiladas, fish, mixed into a salad with grilled tofu and mandolin sliced vegetables...It is very tasty and adds a flavoursome kick, without too much spice!
6 fresh tomatillos, peeled and cut in half
1 hungarian hot wax chili
3 garlic cloves, peeled
1/2 cup fresh cilantro
1 small onion, sliced into 1cm rounds
2 teaspoons salt
juice of 1 lime
zest of 1/2 a lime
1. Preheat BBQ
2. Remove husks from tomatillos and rinse under warm water to remove stickiness. 3. Place tomatillo halves, whole chili and onion slices on BBQ.  Grill both sides, removing the tomatillos when they are soft - about 4 minutes a side. 
4. Add all ingredients to a blender. Roughly puree all ingredients (except coriander) .
5. Salsa can be made 1 day ahead and chilled, covered.
