In a large sauce pan melt butter and saute diced jalapeños over medium heat 1-3 minutes until tender. Add velveeta, cream cheese, and milk and stir until cheeses are melted and smooth.
Stir in green chiles, tomatoes, cilantro, and spices. Serve warm with tortilla chips.
Notes
*use less than a whole jalapeño if you don't want it too spicy.
