You can make cheese sauce with any hard cheese and sodium citrate. For the liquid you can use water, milk, beer or really any beverage you want. Obviously also chillis and hot sauce can be added at any point in the process.
You can also tune the recipe to be thicker or runnier depending on what you use it for.
This is the recipe that I use, they have a specific jalapeno one: https://www.cheeseprofessor.com/blog/sodium-citrate-cheese-sauce
The important part is the ratio of cheese:liquid:sodium citrate.
Fats and oils aren't bad for you, that's propaganda pushed by the sugar industry for decades.

Eat whatever food you like that makes you feel good after you've finished eating, your body knows what's good for it for the most part.
Edit: I think this comment section is pretty good evidence for how well it worked. Loads of people reflexively scoffing at the idea that fat might not be bad for you but no clear arguments as to why.
