First, make potato pancakes by mixing scallions and leftover mashed potatoes. Then divide into four patties (I do this as putting away the potatoes and leave in the firdge. Fry in a pan on medium high for 2 minutes per side. Set aside pancakes.
Next, fry ham 2 minutes per side to reheat in a pan with oil on medium high. Tip: I use same pan as potato pancakes just carefully clean pan with paper towels first.
Now, combine all carnberry mao ingredients.
Next, make the eggs. Add eggs, and butter in a low heat pan. Mix until forms soft wet curds. Then shut the heat off and add the rest of the egg ingredients.
Finally, lets assemble the sandwich. Spread the mayo on each half of the biscuits. Then add ham, then potato pancake, and top with eggs. Now add cheese ontop.
Cheers to fun leftovers becoming an epic brunch sandwich!
