Slice the ciabatta in half lengthwise. Remove most of the insides of the bread to create room for the buffalo chicken. Drizzle both sides with olive oil. Broil on HIGH for 1-2 minutes, until golden.
Generously slather the pesto on both slices.
In a large bowl, combine the shredded rotisserie chicken, ¾ cup of the shredded cheese, parmesan, sour cream, buffalo sauce, chopped cilantro, and scallions. Mix well.
Evenly divide the buffalo chicken among the two bread halves. Top with the remaining shredded cheese.
Broil on HIGH for 1-3 minutes, until cheese is melted and bubbly on top.
Garnish with fresh cilantro.
Enjoy warm with ranch on the side and Vita Ice Peach Mango for a complementary refreshment!
