Creating Hawaiian Roll French Toast is an effortless task when you follow these simple steps:

1. Prepare the Rolls: Slice each Hawaiian roll in half horizontally.
2. Make the Custard: In a large bowl, whisk together the eggs, milk, vanilla extract, ground cinnamon, and salt until well combined.
3. Dip the Rolls: Submerge each roll half in the custard mixture, ensuring they soak up the liquid well.
4. Heat the Pan: In a large skillet or griddle, melt some butter over medium heat.
5. Cook the Rolls: Place the soaked rolls in the heated pan, cut side down. Cook until golden brown, about 3-4 minutes.
6. Flip and Cook: Carefully flip the rolls and cook the other side for an additional 2-3 minutes until they are fluffy and golden.
7. Remove and Serve: Remove from the pan and keep warm in a low oven if needed.

Repeat with the remaining roll halves and adjust butter as necessary.
