Roast tomatillos, onion, and jalapeños on a grill for 2-3 minutes per side. Remove from the grill.
Place tomatillos, onion, and jalapeños in a blender with cilantro, garlic, lime juice and Crove Fajita Rub. Blend until smooth. Optional: Add a pinch of sugar to cut down the acidity.
Place in refrigerator and serve when cooled.
This is great served on chicken tacos, as a dip with tortilla chips, a topping for nachos, and much more!
