Step 1: Flatten each slice of bread using a rolling pin until thin and pliable. Trim crusts if desired.
Step 2: Place one cooked sausage link at one end of each flattened bread slice. Tightly roll the bread around the sausage.
Step 3: In a shallow dish, whisk together eggs, milk, and vanilla extract until well combined.
Step 4: In a separate small bowl, combine granulated sugar and ground cinnamon.
Step 5: Heat a large non-stick skillet over medium heat. Melt 1 tablespoon of butter in the pan.
Step 6: Dip each roll-up into the egg mixture, ensuring all sides are coated.
Step 7: Place the coated roll-ups seam-side down in the skillet. Cook for 2-3 minutes per side, rotating until golden brown and cooked through. Add remaining butter as needed.
Step 8: Immediately roll the cooked French toast sausage roll-ups in the cinnamon sugar mixture until evenly coated.
Step 9: Serve warm with a drizzle of maple syrup if desired. Enjoy!
