1. Begin by flattening each slice of bread with a rolling pin until thin and even.
2. In a medium bowl, mix the softened cream cheese, granulated sugar, and vanilla extract until smooth. Stir in the diced strawberries.
3. Spread a generous amount of the cream cheese mixture on four slices of bread, then top with the remaining slices to form sandwiches.
4. In another bowl, whisk together the eggs, milk, and ground cinnamon.
5. Heat a generous amount of vegetable oil in a large skillet over medium heat. You’ll want enough oil to cover the bottom of the skillet.
6. Dunk each sandwich in the egg mixture, ensuring both sides are well coated.
7. Carefully place the sandwiches in the hot oil and fry until golden brown on both sides, about 2-3 minutes per side.
8. Remove sandwiches from the skillet and drain on paper towels. Dust with powdered sugar if desired.

One of my favorite tips is to use slightly stale bread; it absorbs the egg mixture beautifully and crisps up perfectly. This little trick is something I picked up from my abuela, who always knew how to make the most out of every ingredient.
