Brown and crumble the ground beef in a medium skillet over medium heat. Drain excess grease.
Stir in queso dip and half of the shredded cheddar cheese until well combined.
Transfer the mixture to a 9x13 baking dish and top with remaining cheddar cheese. Broil until bubbly and melted, about 3 to 5 minutes.
Remove from oven and top with shredded lettuce, diced pickles, and diced tomatoes. Drizzle ketchup and yellow mustard over the top. Serve hot with tortilla chips.
Notes
This dip is best served immediately while warm and cheesy. Leftovers can be reheated in the oven.
