Heat 1/4 cup extra virgin olive oil in a large saute pan. Heat the oil without smoking it.Note: I used medium-high heat. Cook the chicken breasts in 2 batches. Cook each batch for 4 minutes total - 2 minutes per side. Chicken breasts will be lightly brown.
Remove the chicken to a plate. Once all the chicken breasts are browned, turn the heat to medium low.
Saute the onion slices for 2 minutes.
Add the crushed garlic and cook 30 seconds.
Add the basil leaves and the reserved pinch of seasoning mix. Stir constantly until the basil leaves are wilted. Remove the onion/basil mixture to a plate.
Add back the chicken breasts to the pan with any juices that was released. Turn up the heat to medium.
Divide the onion/basil mixture into 4. Top each of the breasts with the onion and basil mixture.
Divide the grated povolone into 4. Top each breast with the provolone cheese.
Cover the pan and cook until the cheese melts. About 2 minutes. Turn off the stove.
