When making homemade nachos do you heat the diced tomatoes up?

Or serve them cool, or at room temperature?

I just have a couple of cans of diced tomatoes, a big bag of Tostitos Nacho’s, and a double large bag of shredded cheese. I forgot to buy sour cream.

I have some bacon just in case I want some meat in my nachos.

Just making for one person.

I can make in the oven or microwave. No big game. I just want to save money by making my own Nacho’s.
