The Barrio Santa Rosa, $9.95, from Barrio Charro features Don Guerra's pan levain bread with ripe avocado, pickled red onions, cotija and queso fresco cheeses and balsamic vinegar.
Barrio Charro, 3699 N. Campbell Ave., was brought to Tucson by a "culinary marriage" between the minds behind El Charro Café and Barrio Bread.
