Make a healthy chicken sandwich by combining chopped chicken with mango, mayonnaise, and curry powder and rolling up the creamy mixture in a whole wheat flatbread.
Combine first 4 ingredients (through ground red pepper) in a medium bowl. Add chicken, bell pepper and onion; stir to combine.
Divide chicken mixture evenly among flat breads (about 1/2 cup each), spreading to cover half of each flat bread. Top chicken mixture with 1 lettuce leaf. Roll up and serve.
