Chicken Marsala

Found this on allrecipes.com but I might have something else at home ...

INGREDIENTS:
1/4 cup all-purpose flour
1/2 teaspoon garlic salt
1/4 teaspoon ground black pepper
1/2 teaspoon dried oregano
4 boneless, skinless chicken breast halves
1 tablespoon olive oil
1 tablespoon butter
1 cup sliced fresh mushrooms
1/2 cup Marsala wine

------------------------------------------------------

DIRECTIONS:
In a medium bowl, stir together the flour, garlic salt, pepper, and oregano. Dredge chicken in the mixture to lightly coat.
Heat olive oil and butter in a large skillet over medium heat. Fry the chicken in the skillet for 2 minutes, or until lightly browned on one side. Turn chicken over, and add mushrooms. Cook about 2 minutes, until other side of chicken is lightly browned. Stir mushrooms so that they cook evenly.
Pour Marsala wine over the chicken. Cover skillet, and reduce heat to low; simmer for 10 minutes, or until chicken is no longer pink and juices run clear.
