Heat up oil and drop in potatoes in small batches. Cooking them until crispy and brown. Lay on a sheet tray with paper towels to dry, slip this into a warm oven to keep warm.
After cooking all the potatoes, gather them onto a nice tray (work fast so you keep them warm), sprinkle with salt and pepper. Sprinkle with blue cheese crumbles. Dribble blue cheese dressing all over the top, thinly.
