1cup(3 ounces) reduced-fat shredded Monterey Jack Cheese
3mediumscallions, thinly sliced
2tablespoonschopped fresh cilantro leaves
Adjust an oven rack to the lowest position and heat the oven to 500F degrees for flatbread dough (or 450F degrees for packaged pizza crust).
Roll the flatbread out into one large 12x16-inch rectangle or 4 individual 12x4-inch rectangles and place on a cookie sheet. (Or place the prepared pizza crust on the cookie sheet.)
In a small bowl, mix together the mashed beans and 1/2 cup of the salsa. Spread evenly over the dough.
In a medium bowl toss together the remaining 1/2 cup salsa, chicken and corn. Top the flatbread(s) evenly with the chicken mixture.
Bake until the pizza is spotty brown, 10 to 15 minutes. Remove from the oven and top the hot pizza with the cheese, scallions, and cilantro and place back in the oven. Continue to bake until the cheese melts, 2-3 minutes more.
Serve individual flatbreads or cut the large flatbread/pizza into 8 pieces.
