Chicken Marsala by Laurie

Great recipe for the entire family, kids included. Found in Cooking Light back in 2003...

Clarified butter (butter without the milk solids) is ideal for searing meats because it can be heated to a high temperature without burning. Although you can purchase clarified butter, we detail how to make it below in the first step.
Yield: 4 servings (serving size: 1 chicken breast half, 1 cup pasta, and 1/4 cup sauce)

Ingredients:
4 tablespoons butter, divided
Cooking spray
1 (8-ounce) package presliced mushrooms
2 tablespoons finely chopped shallots
1 tablespoon minced fresh garlic
4 (6-ounce) skinless, boneless chicken breast halves
1/4 teaspoon salt, divided
1/4 teaspoon black pepper, divided
3 tablespoons all-purpose flour
3/4 cup fat-free, less-sodium chicken broth
1/2 cup dry Marsala wine
1/2 cup frozen green peas
2 tablespoons half-and-half
4 cups hot cooked fettuccine (about 8 ounces uncooked pasta)

Preparation
Place 3 tablespoons butter in a small glass measuring cup. Microwave butter at MEDIUM-HIGH 45 seconds or until melted. Let stand 1 minute. Skim foam from surface, and discard. (Mixture will appear separated.) Pour melted butter through a fine sieve over a small bowl, and discard the milk solids. Set the clarified butter aside.
Heat a large nonstick skillet coated with cooking spray over medium-high heat; add mushrooms, shallots, and garlic. Cook 3 minutes or until moisture evaporates; remove mushroom mixture from pan. Set aside.
Place each chicken breast half between 2 sheets of heavy-duty plastic wrap; pound to a 1/4-inch thickness using a meat mallet or rolling pin. Sprinkle both sides of chicken with 1/8 teaspoon salt and 1/8 teaspoon pepper. Place flour in a shallow dish; dredge chicken breast halves in flour.
Add clarified butter to pan, and place over medium-high heat. Add chicken; cook 3 minutes on each side or until lightly browned. Remove chicken from pan. Return mushroom mixture to pan; add broth and Marsala, scraping pan to loosen browned bits. Bring mixture to a boil, reduce heat, and simmer 5 minutes or until reduced to 1 cup. Stir in peas; cook 1 minute. Add 1 tablespoon butter, half-and-half, 1/8 teaspoon salt, and 1/8 teaspoon pepper, stirring until butter melts. Return chicken to pan; cook until thoroughly heated. Serve chicken and sauce over pasta.
