Combine flour, yeast, warm milk, warm water, salt, and olive oil in a bowl. Mix and knead for 5–7 minutes until smooth. Let it rise for 1 hour.
In a bowl, mash feta with olive oil, chopped mint, and black pepper.
Divide the dough into 4 pieces. Flatten each into a small circle, add a spoonful of the filling in the center, then pinch edges to seal and flatten gently.
Heat a non-stick or cast iron skillet over medium heat. Cook each flatbread for 2–3 mins per side until golden and slightly puffed.
Serve warm with an optional drizzle of olive oil or dip in tzatziki.
Notes
For a gluten-free version, substitute all-purpose flour with a gluten-free flour blend.
These flatbreads can be frozen after cooking for a quick snack later.
Feel free to experiment with other herbs like parsley or dill for different flavor profiles.
