In a 9x13" glass baking dish, whisk together eggs, milk, vanilla, honey and salt. Working in batches, soak bread in egg mixture for 1 ½ min., turning once. Melt 1 tbsp. butter in 1 tbsp. oil on a nonstick griddle over medium heat; use a wadded paper towel to evenly coat griddle with melted butter mixture. Add soaked bread in batches to hot griddle, several slices at a time; cook until dark golden-brown (2-3 min. per side), flipping once. Add more butter and oil between batches, as needed. Serve sprinkled with sugar and drizzled with syrup.
