Heat a gas grill to medium-high or build a strong charcoal fire.
Grill the ribs, turning them once, until well browned, even charred here and there, about 6 minutes per side. The ribs should be just a touch rarer than medium-anything less and they will be very chewy. Let them rest 4 to 5 minutes before serving.
This is a standard Mexican salsa that you find everywhere in Mexico. Tomatillos have a natural acidic and fresh note that gives them a little sparkle. (They keep that sparkle even after they're cooked.) Tomatillo salsa is a natural with the flavors of grilled meat, but it is a great do-ahead, have-on-hand salsa to freshen up anything off the grill or out of a skillet.
Scrape the mixture into a small saucepan. Season lightly with salt and bring to a boil over medium heat. Cook, stirring occasionally, until most of the liquid is boiled off and the salsa looks relish-y, about 15 minutes. Cool before using. The sauce can be refrigerated for up to 1 week. If refrigerated, you may want to add a little salt and/or lime juice to the salsa before serving.
