Combine first 7 ingredients and 1 tablespoon cilantro. Shape mixture into 6 (1/3-inch-thick) patties.
Heat a lightly greased large nonstick skillet over medium-high heat. Add patties; reduce heat to low, cover, and cook 8 to 10 minutes per side or until center is no longer pink. Remove from skillet. Wipe pan clean.
Whisk together gravy mix, broth, tomatoes with chiles, and remaining 1 tablespoon cilantro. Cook over medium heat 1 minute or until thickened. Return patties to skillet, and cook until thoroughly heated. Garnish, if desired.
