Brown the ground beef in a large skillet with the Taco Seasoning over medium-high heat, then drain off excess grease. Return skillet of beef to the burner and reduce heat to medium-low.
Add cubed Velveeta cheese and Rotel tomatoes to the beef in skillet. Cook on on medium-low, stirring gently until Velveeta is melted.
Serve with chips, crackers, sliced veggies, over baked potatoes, french fries, or biscuits.
