1. Start by slicing your bread into thick, even sticks. I find that using slightly stale bread yields the best results as it soaks up the egg mixture without becoming soggy.
2. In a large bowl, whisk together the eggs, milk, vanilla extract, cinnamon, and salt until well combined.
3. Place the chopped pistachios and sugar in a shallow dish and mix well.
4. Heat a large skillet over medium heat and add a tablespoon of butter, letting it melt and coat the pan.
5. Dip each bread stick into the egg mixture, allowing it to soak for a few seconds, then roll in the pistachio-sugar mixture to coat evenly.
6. Fry the sticks in the skillet, cooking for 2-3 minutes on each side until they’re golden brown and crispy.
7. Transfer the cooked sticks to a paper towel-lined plate to absorb any excess butter.
8. Repeat with the remaining bread sticks, adding more butter to the pan as needed.

One of my personal tips is to keep the cooked sticks warm in a low oven (around 200°F) while you finish frying the rest. This keeps them crispy and ready to serve all at once.
