In a large skillet, cook beef, onion, green pepper and jalapeno over medium heat until meat is no longer pink and vegetables are tender, 8-10 minutes, breaking beef into crumbles; drain.
Add rice, tomatoes and chiles, broth and seasonings. Bring to a boil, then reduce heat. Simmer, covered, until liquid is absorbed, about 5 minutes. Fluff with a fork. Remove from heat; sprinkle with cheese. Let stand, covered, until cheese is melted.
