Spread those leftover fries around inside the waffle maker, then lock it and let them crisp up for about 8-10 minutes. While they’re cooking get your toppings ready. You don’t have to get fancy here — a fried egg is decadent, but you can use whatever meat, herbs, cheese, or anything else kicking around your fridge.
You don’t have to worry about them “matching” the fries. When your waffle is done, add shredded cheese to the top and press down with the top of the waffle maker for about 15 seconds to melt the cheese. Move the waffle on a plate and pile the toppings on. You can see a step-by-step visual demonstration in the video above (skip to 00:50).
