Grill or bake chicken that has been heavily seasoned with lemon pepper or steak seasoning (or just salt & pepper). Cut chicken into cubes and set aside. Cut lettuce, tomatoes, and mango. Cook rice until tender. For the dressing, blend the ingredients together until smooth. Layer salad with rice on the bottom of your plate, then lettuce, tomatoes, chicken, mango, feta cheese, and tortilla chips. Serve with dressing.
