Make the Prosciutto & Pear Sandwiches:
Layer prosciutto and pears onto two slices of bread. Spread Herbed Parmesan Mayo onto remaining two slices of bread and use those slices to top sandwiches.
Notes
Home Chef Tip: Don't want your pear slices to brown as quickly? Squeeze the juice of half a lemon into a small bowl and add 1/4 cup of cold water. As you slice the pear, dip each slice quickly into the lemon solution, then lightly pat dry on a paper towel.
