In a large non-stick skillet, over medium-high heat, cook the cubed chicken. After about 5 minutes of cooking chicken add the diced bell pepper, taco seasoning and water. Bring to a boil then reduce heat to medium. Continue to stir and cook until chicken is thoroughly cooked and no longer pink in center (about 10 minutes or so). Remove from heat.
Meanwhile, add black beans to a small saucepan. Heat over low heat until chicken is finished cooking. Then remove beans from heat. (You can also heat corn, if desired.)
Take one tortilla and place on a large plate or clean surface. Add a portion of chicken/pepper mixture down the center of tortilla. Top with desired amount of lettuce, black beans, corn, cheese and dressing. Fold up burrito/wrap style and serve immediately. Enjoy!
