Cook pasta according to package directions. Pound chicken with a meat mallet to 1/4-in. thickness. In a large resealable plastic bag, mix the flour, lemon pepper and salt. Add chicken, one piece at a time; close bag and shake to coat.
In a large skillet, heat 1 tablespoon oil over medium heat. Add chicken; cook for 4-5 minutes on each side or until no longer pink. Remove from pan.
In the same skillet, heat remaining oil over medium-high heat. Add mushrooms; cook and stir until tender. Add garlic; cook 1 minute longer. Add wine; bring to a boil. Cook for 5-6 minutes or until liquid is reduced by half, stirring to loosen browned bits from pan. Return chicken to pan, turning to coat with sauce; heat through.
