1Cut pork lengthwise in half, then cut each half crosswise in half. Between pieces of plastic wrap or waxed paper, place each pork piece with cut side up; gently pound with flat side of meat mallet or rolling pin until about 1/4 inch thick.
2In shallow dish, mix flour and salt. Coat pork with flour mixture.
3In 10-inch nonstick skillet, heat oil over medium-high heat. Cook pork in oil 4 to 5 minutes on each side or until golden brown on outside and no longer pink in center. Remove from skillet; cover to keep warm.
4In small bowl, beat water, maple syrup and mustard with wire whisk. Add to skillet; cook and stir about 1 minute or until slightly thickened. Serve sauce over pork.
