For freshly cooked, riced potatoes: Place the washed, skin-on potatoes into a pot and fill it with cold water, enough to fully cover the potatoes. Bring to a boil, then reduce the heat to medium and cook until the potatoes are fork tender (that is, easily pierced with a fork). This usually takes about 30 minutes. Drain the water and allow the potatoes to cool until warm, then peel them and use a potato ricer to rice them. You'll need 300g or about 3 cups of riced potatoes.

For leftover mashed potatoes: You'll need 300g or about 1½ cups of mashed potatoes. Make sure that they're lukewarm or at room temperature when you add them to the dough.

Make the psyllium gel: In a bowl (or the bowl of a stand mixer, if using), mix together the psyllium husk and lukewarm water. After about 30-45 seconds, a gel will form.

In a separate bowl, whisk together the millet flour, sorghum flour, baking powder, salt, pepper and garlic powder.

Add the riced or mashed potatoes, grated cheddar, chopped parsley and the dry ingredients to the psyllium gel, and knead everything together until you get a smooth, supple dough.

Turn out the dough onto a lightly floured surface and shape it into a ball. Divide it into 8 equal portions.

Shape the pieces of dough into balls. Keep the dough balls covered with a dish towel to prevent them from drying out.

Place a dough ball onto a lightly floured surface and dust its top with more flour. Use a rolling pin to roll it out into a large, round flatbread, about 9-9½ inches (23-24cm) in diameter.

Pre-heat a large pan or cast iron skillet over medium to medium-high heat. Place a flatbread into the hot pan or skillet and cook it on the first side for about 1 minute to 1 minute 15 seconds, or until golden brown spots appear underneath. Flip it and brush the top with melted butter. Cook on the second side for about 1 minute or until golden brown spots appear underneath.

Repeat this process with all the other flatbreads. Stack the cooked flatbreads on a plate lined with a paper towel.

Serve warm or cooled to room temperature. They’ll stay wonderfully soft and pliable even when cooled completely to room temperature.
