Lightly grease the bottom and sides of an 8-inch baking dish with 1 tablespoon butter.
Place eggs, milk, salt, and pepper into a shallow baking dish and whisk together.
Place a single piece of bread onto a clean surface and using a rolling pin, roll the piece of bread until completely flattened.
In a mixing bowl combine bacon, shredded cheese and green onions/chives and toss together.
Scatter 2 heaping teaspoons of the bacon mixture onto the flattened bread and roll up.
Place the roll on a cutting board, seam side down and slice in half, widthwise.
Carefully dip both rolls into the egg mixture until completely covered and place into the greased baking dish, standing up, side by side.
Repeat steps 4 through 7 until all of the bread and bacon/cheese have been used and the baking dish is filled with Savory French toast roll ups.
Pour remaining egg mixture over the baking dish, cover with foil and refrigerate for 1 hour.
Preheat oven to 350˚F.
Place covered baking dish into the oven and bake for 25 to 30 minutes.
Remove French toast from oven, uncover and randomly dot the top with remaining tablespoon butter.
Place baking dish back into the oven and continue to bake for an additional 10 minutes or until the butter has melted and the top has browned.
Allow French toast to cool slightly before topping with butter (optional) and serving.
