Cut a horizontal slit through thickest portion of each chicken breast half to form a pocket. Stuff about 3 tablespoons cheese mixture into each pocket; close opening with a wooden pick.
Sprinkle chicken evenly with salt and pepper.
Heat a large cast-iron skillet over medium-high heat. Coat pan with cooking spray.
Add chicken to pan; cook 4 minutes. Turn chicken over; place pan in oven.
Bake at 400 for 25 minutes or until chicken is done.
Let stand 5 minutes. Discard wooden picks.
Cut chicken diagonally into 1/2-inch-thick slices.
Serve with pan juices.
Combine 1/4 teaspoon salt, 1/4 teaspoon freshly ground black pepper, and 1 pound trimmed asparagus on a jelly-roll pan coated with cooking spray; toss gently.
Bake at 400 for 10 minutes or until asparagus is crisp-tender.
Place asparagus in a large bowl; toss with 1 tablespoon butter and 1 tablespoon chopped fresh chives. Complete the meal with a sliced baguette and a glass of crisp white wine.
