In a small bowl, combine softened butter with garlic powder, fresh parsley (if using), salt, black pepper, and dried oregano (if using). Mix thoroughly until a smooth, spreadable paste forms. If opting for fresh garlic, sauté it briefly in a small amount of butter until fragrant, then incorporate it into the spread.

In a medium bowl, thoroughly combine the shredded mozzarella, cheddar, and Monterey Jack cheeses, ensuring an even mixture.

Lay out the bread slices. Generously apply the prepared garlic butter mixture to one side of each slice. Flip the slices so the buttered side faces down. On two of these slices, mound the combined cheese mixture in the center, leaving a small border. Top with the remaining bread slices, buttered side up, to form the sandwiches. For an ultra-golden, crispy crust, a very thin layer of mayonnaise may be spread on the exterior buttered sides.

Heat a nonstick skillet or cast-iron pan over medium heat. Place one sandwich in the pan and cover with a lid to promote even cheese melting. Grill for 2 to 3 minutes per side, or until the bread is golden brown and crispy. Adjust heat as necessary to prevent burning. Carefully flip the sandwich with a spatula, pressing lightly to ensure full contact with the pan. Repeat the process for the second sandwich, or cook both simultaneously if pan size permits.

Once both sides are golden and the cheese is fully melted and stretchy, transfer the sandwich to a cutting board. Allow it to rest for 1 to 2 minutes to prevent scorching from the molten cheese. Slice diagonally or into fingers for dipping. Serve immediately with your preferred accompaniment, such as soup or salad.
