In a large skillet over medium-high heat, brown the ground beef, breaking it up as it cooks.
Drain excess fat from the beef and transfer it to a 3- to 4-quart slow cooker.
Add cream cheese, Velveeta, salsa, green chilies, and taco seasoning to the slow cooker. Stir slightly to begin combining.
Cover and cook on low for 1 1/2 to 2 hours, stirring occasionally, until the dip is hot and all ingredients are melted and well blended.
Serve warm with tortilla chips.
Notes
This dip can be kept warm during serving by switching the slow cooker to 'Keep Warm.' It pairs perfectly with tortilla chips, toasted baguette slices, or fresh veggies.
