Split open rolls and remove most of the soft insides, leaving a bed to hold the meat mixture. Toast the rolls and set aside. While the meat is cooking, melt the butter in a medium-size pot over medium-high heat. Stir in the flour and cook about 1 minute. Whisk in milk, bring up to a bubble and let thicken, about 2 minutes. Turn off heat and stir the cheese. To serve, place a scoopful of the meat mixture onto the bottom of the rolls, then top with the cheese sauce and replace the top of the roll.
