Using a meat mallet (or the back of a small pan) pound out the pork until it’s 1/4” thick. Season well with salt and pepper. Combine breadcrumbs and basil; set aside. Whisk together egg and buttermilk; set aside. Dredge cutlets in flour, then buttermilk mixture and finally breadcrumbs. Place in single layer in refrigerator for 30 min to allow breading to stick and dry. Heat oil in large, heavy skillet over med heat and fry cutlets on each side until golden brown (approx. 2-3 min per side). If necessary, finish in 350° oven for 5-8 min until internal temp reaches 145° (pork will be slightly pink in center).
