Let's make a ham, egg, and cheese breakfast bagel sandwich that reminds me of the bagel sandwiches I loved so much in Old Montreal. Made with my mom's fluffy Japanese Bagel recipe, this bagel sandwich starts with a crispy sesame bagel, topped with soft scrambled egg, a slice of cheese, and some ham. Since I'm making a huge Christmas Eve Dinner, this easy egg sandwich will be the easiest way to get my day started in 15 minutes!
