1 teaspoon margarine or butter 
4 small skinless, boneless chicken breast halves (1 pound) 
1/2 cup fat-free chicken broth 
2 tablespoons balsamic vinegar 
1/8 teaspoon coarsely ground black pepper 
4 thin slices cooked ham (2 ounces) 
4 thin slices part-skim mozzarella cheese (2 ounces)
5- to 6-ounce bag prewashed baby spinach

 
In nonstick 12-inch skillet, melt margarine over medium-high heat until hot. Add chicken and cook 5 minutes. Reduce heat to medium and turn chicken over; cover and cook until chicken is golden brown and just loses its pink color throughout, about 5 minutes longer.
Increase heat to medium-high. Stir in broth, vinegar and pepper; cook, uncovered, 1 minute. Remove skillet from heat; top each chicken breast with a slice of ham, then a slice of cheese. Cover skillet until cheese melts, about 3 minutes.
Arrange spinach on large platter; top with chicken breasts and drizzle with pan sauce.
