In a large pot (about 6-quarts), combine the diced tomatoes, tomato sauce, chicken broth, barley, water, chili powder, cumin, dried oregano and cayenne (if using). Stir well. Bring the mixture to a boil over high heat and add the chicken. Stir to combine. Reduce the heat to medium-low, cover, and simmer the chili for 40 minutes, until the barley is tender and chewy and the chicken is no longer pink. Stir occasionally, while it simmers to prevent sticking and to make sure it stays at a steady simmer. After 40 minutes, add the beans and corn. Stir to combine and simmer for five more minutes. Serve the chili with optional garnishes, if desired.
