1 (1 pound) pork tenderloin
1/3 cup all-purpose flour
1/4 teaspoon salt
1/4 teaspoon pepper
1 tablespoon butter
3 green onions
1/3 cup white wine or chicken broth
1/2 cup fat-free evaporated milk
4 teaspoons Dijon mustard
Cut pork widthwise into 6 pieces; flatten to 1/4-in. thickness. In a large resealable plastic bag, combine the flour, salt and pepper. Add pork, a few pieces at a time, and shake to coat. In a large nonstick skillet, brown pork in butter over medium-high heat. Remove and keep warm.
Slice green onions, separating the white and green portions; reserve green portion for garnish. In the same skillet, saute the white portion of green onions for 1 minute. Add wine or broth. Bring to a boil; cook until liquid is reduced to about 2 tablespoons. Add milk. Reduce heat; simmer, uncovered, for 1-2 minutes or until slightly thickened. Whisk in mustard. Serve pork with Dijon sauce. Garnish with reserved green onions.
