Pork Milanese with Mashed Sweet Potato

Prick sweet potatoes in several places with a fork. Place on a plate and microwave on High until tender all the way through, 10 to 15 minutes.

Meanwhile, place flour in a shallow dish and egg in another dish. Combine breadcrumbs and Parmesan in a third dish. Press pork medallions down with your hand so they are all about 1/2 inch thick. Sprinkle with 1/4 teaspoon each salt and pepper. Coat both sides of the pork first in the flour, shaking off any excess, then dip in egg. Finally, coat on both sides with the breadcrumb mixture, pressing to help the crumbs stick.

Heat oil in a large nonstick skillet over medium heat. Add the pork and cook, turning once, until golden brown and an instant-read thermometer inserted in the center registers 145 degrees F, 4 to 5 minutes per side (see Tip, below). Transfer to a clean plate and let rest while you finish the sweet potatoes.

When the sweet potatoes are cool enough to handle, cut open and scoop the flesh into a medium bowl. Mash with sour cream, sage and the remaining 1/4 teaspoon each salt and pepper. Serve the pork with the mashed sweet potato and a lemon wedge, if desired.
