Dirty fries are awesome.
If you're doing it properly then really you want to be slicing potatoes, lightly frying them into chips and then using those, but that takes more time and effort than I'd normally have spare on a weekday evening. But, for 10 minutes prep you can quite easily make them using some frozen chips.
In the picture, I've used low-fat cheese, but be aware it doesn't melt as nicely as the proper stuff (it doesn't turn into a runny gloop). Tastes fine, but isn't quite the same.
