Science (or maybe pseudo-science) tells us that breakfast is the most important meal of the day. So why waste it? Don’t eat plain eggs or plain toast. Don’t skimp on cheese or sauteed vegetables. And definitely don’t forget a crispy slice of prosciutto. There’s one way to get all of these in one: A breakfast sandwich. And not some soggy fast food concoction—a real, homemade breakfast sandwich. Wheaties as the breakfast of champions? No. Breakfast sandwiches that will impress any morning-after guest? Definitely.
