Trim the crusts off the bread slices and flatten each slice with a rolling pin.
In a small bowl, mix the crumbled sausage and 2 tablespoons of the sugar together.
Place about 1 tablespoon of the sausage mixture on one end of each flattened bread slice and roll it up tightly.
In a separate bowl, whisk together the eggs, milk, vanilla extract, and cinnamon until well combined.
Heat a skillet over medium heat and add 1 tablespoon of butter.
Dip each roll-up in the egg mixture, ensuring they are fully coated, then place them seam-side down in the skillet.
Cook for about 2-3 minutes on each side, or until golden brown and cooked through. Add more butter as needed for cooking.
Once cooked, roll the French toast roll-ups in the remaining sugar and serve warm with maple syrup.
