To a medium to large size pot, add the macaroni. Heat pot on low heat and add butter, granulated garlic, salt, pepper, cumin and green chiles (including the juice from the can). Gently stir together.
To the pan, add half & half, shredded cheddar cheese, and shredded hot pepper jack cheese. Stir together.
Carefully do a quick taste test and add more salt if needed. Turn the heat up slightly and gently stir until the desired consistency is reached.
Top with thin tortilla chips, crumbled tortilla chips or corn chips.
Serve right away while warm.
