Cut crusts from slices of white bread. Flatten bread with a rolling pin. Spread desired filling on 1 side of each slice of bread. Consider combining cream cheese with fruit or peanut butter with bananas. Tightly roll up the slice of bread. Continue for remaining slices. In a shallow dish, beat eggs and milk with whisk. In another dish, mix sugar and cinnamon. In a skillet, melt butter over medium heat to coat inside of skillet. Dip each roll in egg mixture and place in skillet. Cook in batches of 3 or 4, turning until roll is browned. Dip into cinnamon sugar, and roll until completely covered. Serve immediately.
