Preheat the broiler to 450 degrees
On a large sheet pan with parchment paper, arrange the tomatillos,, jalapenos, white onions and garlic. Should be 1 layer so all veggies get a fair char.
Spray veggies with olive oil spray so evenly covered.
Salt and Pepper generously.
Place in over on 2nd to top rack and leave for 15-20 min or until softened and cooked through.
For the last 5 minutes place on top rack and crank the broiler as high as it will go.
Allow veggies to have burnt edges or an even char all around.
Remove from oven and let cool.
Place in food processor and add in cilantro and lime jiuce.
Pulse until desired consistency. Salsa can be chunky or thin - you decide!
Taste and salt as required.
Serve with nacho chips, pour over meat as a sauce or jar as gifts. Keep in fridge - best served cooled.
