White pizza grilled cheese

From Kitchen Treaty.

White pizza in grilled cheese form.  Man this smelled good cooking.  Fast dinner if you've got all the ingredients on hand too.

½ cup whole milk ricotta cheese
2 teaspoons extra virgin olive oil
1 small clove garlic, minced
1 tablespoon chopped fresh basil (or 1 teaspoon dried)
2 teaspoons chopped fresh oregano (or ½ teaspoon dried)
¼ teaspoon kosher salt
Freshly ground black pepper to taste
¼ cup shredded Parmesan cheese
8 ounces mozzarella cheese, thinly sliced
8 slices white bread (6 slices if your bread is on the larger side)
Butter

In a small bowl, mix together the ricotta, olive oil, garlic, basil, oregano, salt, and black pepper.
Refrigerate for at least an hour (or up to 24 hours) to allow the flavors to develop.
Lay down the bread slices and, using a butter knife, spread the ricotta mixture evenly on each piece.
The ricotta mixture should coat the insides of both pieces of bread.
Lay the mozzarella slices evenly on every other piece of bread (one side of each sandwich).
Sprinkle with Parmesan cheese and close the sandwiches by place both cheesy insides together.
Butter the outsides of the bread and cook in a large frypan until both sides are lightly golden brown and the cheese is melted.
