For a crisp and delicious breading option, use Ritz Crackers.
pork tenderloin, trimmed
Salt and pepper
crushed Ritz Crackers
Kaiser rolls, dill pickle chips, yellow mustard, onion slices
Cut tenderloin crosswise into four equal pieces. Butterfly each piece by cutting about halfway into the thickness of the meat, then slicing partway into each side to create flaps. Spread open each piece of pork. Place pork between sheets of plastic wrap. Using the flat side of a meat mallet, pound pork to 1/4 inch thick; season with salt and pepper
Whisk together eggs, Dijon and garlic powder in a shallow dish. Place cracker crumbs in another shallow dish.
Heat 1/4-inch oil in a saute pan over medium-high heat. Dip pork in egg mixture, letting excess drip off. Dredge pork into cracker crumbs, pressing to adhere. Fry pork in oil, turning once until meat is golden brown, 2-4 minutes per side.
