In a skillet over medium heat, add the ground beef, onion, and garlic. Cook until the beef is browned and the onion is translucent, about 7-10 minutes.

Drain excess fat, then stir in salt, black pepper, and paprika. Remove from heat.

In a bowl, combine the shredded cheddar cheese and softened cream cheese until well mixed.

Preheat the oven to 375°F (190°C).

Spread the beef mixture evenly on the slices of bread.

Top each with the cheese mixture.

Place the assembled melts in a baking dish and bake for 15 minutes, or until the cheese is bubbly and golden.

Remove from the oven, let cool slightly, then serve warm.
