Season the steak with salt and pepper. Grill or pan-sear the steak over medium-high heat until cooked to your liking. Let it rest for a few minutes, then chop into small pieces.

Melt the Cheese Mixture

In a large saucepan over medium heat, add the cream cheese and milk. Stir until melted and smooth.

Add Cheeses and Seasonings

Stir in the sharp cheddar and Monterey Jack cheeses. Add garlic powder, onion powder, cumin, and additional salt and pepper to taste. Continue stirring until all cheeses are melted and well combined.

Combine Ingredients

Add the chopped steak and diced green chiles to the cheese mixture. Stir until everything is evenly combined and heated through.

Garnish and Serve

Remove from heat and stir in the chopped cilantro. Serve warm with tortilla chips or as a topping for your favorite dishes.
