Optional: Confectioners’ sugar and halved strawberries
In a shallow bowl, whisk together eggs, milk and salt. Spread preserves on 4 slices of bread; top with remaining bread. Trim crusts; cut each sandwich into 3 strips.
Preheat griddle over medium heat. Lightly grease griddle. Dip both sides of strips in egg mixture; place on griddle. Cook until golden brown, about 2 minutes per side. If desired, cut into squares and alternately thread onto skewers with halved strawberries. If desired, dust with confectioners’ sugar.
