1. Slice pork tenderloin lengthwise, cutting to, but not through, other side. Open halves, laying pork flat. Place plastic wrap over pork; pound to 1/4-inch thickness using a meat mallet or small heavy skillet. Cut pork crosswise into 4 steaks; sprinkle with salt.
2. Heat a large nonstick skillet over medium-high heat. Coat pan with cooking spray. Add pork; cook 3 to 4 minutes on each side or until done. Transfer pork to a plate. Reduce heat to low.
3. Combine vinegar and remaining ingredients in a small bowl, stirring with a whisk. Stir vinegar mixture into pan drippings; cook 1 minute. Return pork to skillet; remove from heat. Let stand 2 to 3 minutes or until thoroughly heated, turning often.
