Mix yeast and salt into flour with a whisk. Add the warm milk and water and knead just until the liquids are absorbed.
Mix in the olive oil and knead until the dough is smooth (around 10 minutes).
Make a ball out of the dough, cover it with vegetable oil, and set it aside in a warm place for an hour, or until it has doubled in size.
When the dough has risen enough, divide it into six pieces and roll each one into a ball.
Each flatbread should be rolled out and put on a pan with medium-high heat.
Take 5–6 minutes to cook (2.5-3 minutes on each side).
Each flatbread should make a pocket in the middle when you flip it over.
Spread oil on each hot flatbread, then sprinkle parsley and chili flakes on top.
