Drizzle olive oil on one side of each slice of bread. Lay two bread slices oil side down. Place one slice each of provolone and mozzarella on both pieces of bread. Top the cheese with half the spinach for each sandwich and place remaining cheese on top of that. Place the remaining slices of bread on top to form a sandwich, oil side out.

Heat a non stick griddle, grill pan or fry pan to medium heat. Place sandwiches on hot pan. Cook 2-4 minutes until golden brown. Flip sandwiches over and cook until browned and cheese melted.

Slice each sandwich in half and serve along side soup.
