Heat 12-inch nonstick skillet over medium-high heat. In separate shallow bowls, place 1/3 cup dressing and flour. Dip pork pieces into dressing; coat with flour. Add pork to skillet; cook 1 to 2 minutes on each side or until brown. Meanwhile, in small bowl, mix broth and 2 tablespoons dressing.
Reduce heat to medium; add broth mixture to skillet, moving pork with wooden spoon to scrape up any brown bits. Add asparagus; cover and cook 2 to 3 minutes or until asparagus is crisp-tender and pork is no longer pink in center.
