Begin by boiling the medium potato until it is fully cooked.
Once cooked, mash the potato in a bowl until smooth.
In the bowl, combine the mashed potato with shredded cheese, avocado, salt, pepper, and the large egg, mixing everything together thoroughly.
Heat the butter or olive oil in a frying pan over medium heat.
Spoon the potato mixture into the pan, shaping it into waffles, and cook until they are golden brown on both sides.
Serve the waffles hot, and feel free to add optional toppings like everything bagel seasoning, chili flakes, chives, or a drizzle of honey.
