Combine all the ingredients excluding the bunz in a medium bowl and mix well. Slice 2 large bunz in half. Place them in small baking pan with sides, cut side up, and pour liquid mixture over them. Let soak for a few minutes then flip them over a couple times to help saturate evenly.
Use medium low heat to give enough time to cook the bunz all the way through before they burn. Place them in the heated skillet cut side up so that the mixture doesn’t drain out. Cook with a generous amount of butter or fat of your choice. Once the French toast begins to set and turn golden on the bottom, flip over and fry on the other side adding more fat as desired. They will puff slightly when cooked through. Remove from pan and set aside.
