Start by cooking the sausage links in a skillet over medium heat until fully cooked. Set them aside to cool slightly.

Remove the crusts from each slice of bread. Use a rolling pin to flatten each slice into a thin, even layer.

Place a cooked sausage link at the edge of each flattened bread slice. Roll the bread tightly around the sausage, pressing gently to seal.

In a shallow bowl, whisk together the eggs, milk, vanilla extract, cinnamon (optional), and a pinch of salt.

Dip each roll-up into the egg mixture, coating all sides lightly without over-soaking.

Heat butter in a skillet over medium heat. Place the roll-ups seam-side down in the skillet. Cook and turn until golden brown on all sides, about 2-3 minutes per side.

Serve the sausage french toast roll-ups warm, drizzled with maple syrup, and with fresh fruit on the side if desired.
