Here's a refreshing twist on the usual tomato-based salsa: a savory blend of grilled tomatillos, onion and pepper. Grilling the vegetables gives the salsa a smoky undertone.
Heat an outdoor or stove-top grill. Keeping them in their husks, brush the tomatillos, the jalapeno, and onion halves lightly with the olive oil. Grill the vegetables until soft, about 15 minutes.
Remove the husks from the tomatillos. Place grilled vegetables into the bowl of a food processor. Add the lime juice, salt, sugar, cumin, and cilantro. Pulse the mixture until salsa is formed, about 8 pulses. Serve with warm tortilla chips.
When you grill the tomatillos in their husks they get cooked through but not charred. Adjust the salsa's heat with more or less jalapeno.
