Ingredients:
- 2 – 2 1/2 cups mashed potato (cold)
- 1 large egg or 2 small eggs
- 1/3 cup plain flour
- 1 cup grated melting cheese
- 8 oz / 250g bacon (diced)
- 1/2 cup scallions/shallots (thinly sliced)
- 1/4 tsp salt
- 2 cups panko breadcrumbs OR 3/4 cup plain flour
- 4 to 6 tbsp oil (any cooking oil)

Directions:
- In a bowl, mix together the mashed potato, egg, flour, cheese, bacon, scallions, salt, and pepper until just combined.
- Spread the panko or flour on a large plate or baking tray.
- Measure out 1/4 cup of the potato mixture or use a slightly heaped ice cream scooper and drop it onto the panko/flour. Repeat this step until you fill the plate or baking tray, making sure not to crowd them.
- Using a spatula or the base of a cup, pat each portion down to about 1.5 cm (2/3 inch) thick patties. Flip them and coat the other side with panko/flour. Set aside and repeat with the remaining mixture.
- Heat half of the oil in a large skillet over medium-high heat. Cook six patties at a time until they are golden brown on each side, about 2 minutes per side.
- Remove the cooked patties onto a paper towel-lined baking tray. Cook the remaining patties in the same way.
- Serve hot!
