I found this wonderful Breakfast Bagel recipe off a great toaster-oven
website having lots of such recipes!
Prep: 5 min, cook: 10 min
* poppy seed bagel, split and toasted
* butter or mayonnaise
* slices prosciutto
* slices vidalia onions or yellow onions
* slices swiss cheese
* spicy yellow deli mustard
Spread the toasted bagel halves with butter or mayonnaise. Arrange the
bagel halves, cut side up, on a toaster oven tray. Layer the prosciutto
slices on top of one bagel half; top with onion and cheese slices. Slide
the cheese topped bagel half into a toaster oven, and heat on the top
brown or toast setting until cheese melts. Top with second bagel half.
Serve the sandwich immediately with deli mustard.
