TOMATILLO AVOCADO SAUCE
ASSEMBLY
Process tomatillos, avocado, cilantro, onion, garlic, 2 chiles, and salt in a blender until smooth, about 1 minute. Taste and, if desired, add 1 or 2 additional chiles, processing to incorporate. Add ¼ cup water, and process until mixture is slightly loosened but thick enough to dollop, adding remaining water as needed to reach desired consistency. Taste sauce, and season with additional salt, if desired.
Split each roll horizontally. Spoon about 1 tablespoon sauce onto bottom of each roll, spreading evenly. Top each with a scant 3 tablespoons carnitas , and finish with a little more sauce, if desired. Cover with tops of rolls. Serve with remaining sauce on the side.
