Flatten each slice of bread to about 1/4 inch thick using a rolling pin.

Lay a cooked sausage link at one end of each flattened bread slice and roll tightly.

In a large shallow bowl, whisk together the eggs, milk, vanilla extract, and sugar.

Dip each assembled roll-up into the egg mixture, ensuring all sides are coated.

Preheat a skillet over medium heat with butter, then cook roll-ups seam side down for 2-3 minutes per side.

Remove from skillet, drizzle with maple syrup, and serve immediately.
