Maple Syrup: Use pure maple syrup for that rich sweetness—no fake stuff here, please!
Dijon Mustard: A zesty kick that balances the sweetness of the maple syrup perfectly.
Eggs: Fresh eggs are essential; they provide a creamy filling and protein boost.
Bacon or Sausage: Choose your favorite for that savory element; crispy bacon adds extra crunch and flavor.

Let’s Make it together
Preheat Your Oven: Start by preheating your oven to 375°F (190°C) so it’s hot and ready when you are.
Prepare the Croissants: Slice each croissant in half lengthwise, ensuring not to cut all the way through; they should open like a book.
Cook Your Protein: In a skillet over medium heat, cook bacon or sausage until crispy and golden brown. Drain on paper towels before assembling.
Whisk the Eggs: In a bowl, whisk eggs with salt and pepper until frothy. Pour into the same skillet used for meat, cooking until softly scrambled.
Assemble the Sandwiches: Spread Dijon mustard on one side of each croissant half. Layer cheese, eggs, bacon or sausage, spinach, and drizzle with maple syrup before topping with the other half.
Bake Until Perfect: Place sandwiches on a baking sheet and bake for 5-7 minutes until heated through and cheese is melted. Enjoy while warm!
