The tortillas we use here are those crisp, crunchy, corn-gritty triangles that somehow always feel like a guilty pleasure. Although having said that, I know only that "guilty pleasures" exist, but I have never understood the point of feeling guilty about pleasure. Rather, I see plenty of reasons for feeling guilty about failing to take pleasure in things.
When I plan to make this, I tend to take a big pack of frozen corn out of the deep freeze at breakfast time, in readiness for a super-quick, fantastically soothing, mellow-yellow and very pleasing supper that night.
Use whatever cheese you like; mostly I go for Cheddar since I always have some in the fridge, but I am happy about using up other bits and pieces. If children are eating, it's wise to omit the chillis - unless they're being very annoying.
