Creating the Spinach Artichoke Grilled Cheese is simple with these step-by-step instructions:

1. Prepare the Filling: In a mixing bowl, combine the softened cream cheese, artichoke hearts, chopped spinach, mozzarella cheese, Parmesan cheese, mayonnaise, and minced garlic. Mix well until combined. Season with salt and pepper to taste.

2. Assemble the Sandwich: Spread a generous amount of the spinach artichoke mixture onto two slices of bread. Top with the remaining slices to create two sandwiches.

3. Butter the Bread: Spread butter evenly on the outer sides of each sandwich. This will help achieve that perfect golden crust when grilled.

4. Heat the Pan: Preheat a non-stick skillet or griddle over medium heat. Once hot, carefully place the sandwiches onto the skillet.

5. Grill the Sandwiches: Cook for about 3-4 minutes on one side, or until golden brown. Flip the sandwiches carefully using a spatula, and cook for an additional 3-4 minutes.

6. Melt the Cheese: Continue grilling until the cheese is fully melted and the bread is crispy.

7. Serve Hot: Once done, remove the sandwiches from the skillet, allow them to cool for a minute, then slice in half for serving.
