Cook the sausage in a skillet over medium heat until browned and fully cooked, about 8-10 minutes. Transfer to a plate to cool.

In a shallow bowl, whisk together eggs, milk, cinnamon, and vanilla extract until smooth.

Trim the crusts off the bread and flatten each slice with a rolling pin to about 1/4 inch thick.

Place a cooked sausage link at one end of each flattened bread slice and roll tightly, sealing the edges.

Melt butter in the skillet over medium heat. Cook the roll-ups seam-side down until golden brown, about 2-3 minutes on each side.

Remove from skillet and serve with toppings of choice, such as maple syrup or powdered sugar.
