Cook the ground beef or sausage in a skillet over medium heat until browned. Drain excess grease.

Cube the Velveeta and cream cheese to ensure even melting.

In your slow cooker, combine all cheeses, Rotel tomatoes (with juices), and cooked meat. Stir well.

Cover and cook on low for 2 hours, stirring occasionally until melted and creamy.

Serve warm with tortilla chips for dipping.
