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 mixture to a 9x13 inch baking dish. Top with remaining cheddar cheese and broil until bubbly and cheese is melted, about 3 to 5 minutes.
Remove from oven. Top with shredded lettuce, diced pickles, and diced tomatoes. Drizzle ketchup and mustard over the top. Serve hot with tortilla chips.
Notes
This dip is great for gatherings and can be customized by adding cooked bacon for an extra smoky flavor.
