Slice each chicken breast in half diagonally, nearly all the way through, and open to form two even halves.
It is easier to cut the chicken if it is partially frozen.
Place the breasts in a shallow baking dish and cover with olive oil.
Add salt and pepper to taste and allow to marinate for 30 minutes.
Meanwhile, combine goat cheese, marjoram and garlic and mix well to make a paste.
It is easier to do this if the goat cheese is at room temperature.
Pour some of the olive oil from the baking dish into a frying pan and heat to medium/high.
Preheat the oven to 375 degrees.
