Slice off the crusts on the bread. Use a rolling on to flatten each piece of bread. Place a sausage link on the front edge of the bread. Roll up tightly, like a taquito. Preheat skillet over medium heat, make sure to grease well with butter. Add eggs, milk, sugar, cinnamon, vanilla, and flour together in shallow dish. Dip sausage roll ups into the mixture, rolling gently coat all sides, and place in skillet. Cook for a few minutes, turning gently as you go until they are golden brown. Serve with syrup. Enjoy!
