Season chicken with salt and pepper. In a large nonstick skillet, brown chicken in hot butter or olive oil over medium heat for 2 minutes on each side. Remove from skillet; add mushrooms, leeks, and shallot. Cook and stir until mushrooms are tender. Return chicken to skillet; add 1/2 cup of the broth, Worcestershire sauce, and artichoke hearts. Bring to boiling; reduce heat. Simmer, covered, 10 minutes or until no pink remains in chicken (170 degrees F).Advertisement
