Heat a cast iron skillet to medium and let it warm up. Butter the outside of both slices of bread. Place one side down and lay a piece of cheese on it. Gently smooth a layer of raspberry preserves on it to create a sticky bed for the spinach. Place the spinach on the preserves and then top with the other piece of bread, butter side up. 

I like to place a cookie sheet or something over the skillet to trap all the heat and make the grilled cheese extra gooey. Keep it on one side for about 5 mins or until golden brown and crispy. Using a spatula, quickly flip your grilled cheese to the other side and repeat.

Once that side is done, transfer it to a plate and dip in my super yummy homemade ranch!
