Dump all the roasted vegetables into a food processor (not a blender) and add the roughly chopped cilantro and the green parts of the scallions. Puree until smooth. Taste and season with more salt if necessary. Cover and refrigerate the salsa until ready to serve or up to 24 hours.☞ TESTER TIP: If your salsa seems exceptionally thick, you can thin it with a little water or a squeeze of lime juice.
