In a big bowl mix together the mashed potatoes, flour, 2 eggs, onions, a little salt and pepper and any extras you want to add in. Heat a skillet with a little olive oil on medium heat. Take about ½ a cup of your mixture and make a patty. It should be easy to form and not to sticky. If it's to dry add another egg and if it's to sticky add a little more flour. Fry your "patty" in the hot oil until golden brown on both sides. I always make one and then taste it to see how much more salt and pepper to add. Add the toppings that suit you and enjoy!
