To prepare a marinade, combine 1 jar of Sweet and Hot Mustard, cider vinegar and soy sauce. Place meat in a large plastic bag and cover with marinade. Marinate at least 2 hours, turning occasionally.
Remove meat from marinade and dry well. Discard marinade. Season with salt and black pepper. Heat heavy pan with oil until very hot. Sear meat and brown on all sides. Once browned, glaze with remaining Sweet and Hot Mustard.
