Almost Olive Garden Chicken Marsala

2 boneless-skinless chicken breast halves

1/2 c flour

1 1/2 tsp salt

1 tsp dried oregano leaves

2 tbsp olive oil

2 tbsp butter

1/2 c mushrooms, sliced

1/4 c Marsala

Slice each breast half into 3 pieces. Place a piece of chicken between 2 sheets of plastic wrap. Using the flat side of a meat mallet, flatten each piece to 1/4" thickness. Repeat with remaining pieces. Combine flour, salt, and oregano. Coat both sides of chicken pieces in flour mixture, shaking off excess. In a skillet, heat oil and butter over medium heat. Cook chicken for 2 minutes on the first side (light brown). Turn chicken over. Add mushrooms to skillet. When chicken is light brown, add wine. Cover and simmer for 10 minutes.
