Preheat Oven on Convection to 425° or Air Fryer to 400°.
Trim excess fat off pork & discard. If using pork loin, cut into 2" thick slices. Place slices or pork chops on to cutting board. Cover in plastic wrap. With a meat mallet or bottom of a saute pan, pound pork to 1/4"-1/2" thickness. Discard plastic wrap. Lightly sprinkle pork with salt, if desired.
Place pretzels in zip top bag. With meat mallet or saute pan, crush pretzels to crumbs. Pour crumbs into shallow dish.
In another shallow dish, whisk wet ingredients.
Spray air fryer or cooling rack (if using oven) with pan spray. Dip pork into egg mixture, then into pretzels, patting crumbs on, until coating completely. Set in air fryer, or on cooling rack on top of a baking sheet.
Put in air fryer for 6-8 minutes, or in oven for 10-15 minutes or until pork registers at 145°F.
Serve with Lightened Up Mushroom Gravy (recipe link in notes) or enjoy with mustard.
