Directions

Make the sauce: In a small bowl, whisk together maple syrup, Dijon mustard, apple cider vinegar, garlic powder, black pepper, and salt until smooth. Set aside.

Assemble the sandwiches: Slice croissants in half horizontally. Spread the maple mustard sauce on the bottom half of each croissant.

FAQs
