Follow these simple steps to prepare your grilled cheese hot dogs:

1. Prepare the Skillet: Heat a non-stick skillet over medium heat. This ensures even cooking and prevents sticking.
2. Flatten the Buns: Using a rolling pin, flatten each hot dog bun to create a wider surface. This helps hold more cheese and the hot dog.
3. Butter the Buns: Spread 1 tablespoon of softened butter on the outside of each bun. This adds a rich flavor and helps achieve a crispy, golden-brown crust.
4. Add Cheese to Buns: Place the buttered buns butter-side down in the skillet. Top each bun with 1/3 cup of shredded Monterey Jack and cheddar cheese.
5. Grill the Hot Dogs: Slice each hot dog lengthwise, leaving it connected. Place them on the skillet flat side down and grill for about 2 minutes, or until browned. Flip and grill for another minute to ensure even cooking.
6. Assemble the Hot Dogs: Place the grilled hot dog in the center of each bun. Sprinkle with an additional 3 tablespoons of cheese.
7. Grill the Assembled Hot Dogs: Close the bun and continue grilling until the cheese is fully melted and the bun is crispy.
8. Serve and Enjoy: Transfer the grilled cheese hot dogs to a plate and serve with your favorite condiments.
