Hi Sonia -
Try this recipe
Subway Flatbread
2 tablespoons sugar
1 teaspoon salt
1 cup of warm water
1 tablespoon active dry yeast
3 tablespoons milk
1/4 cups butter
6 cups all-purpose flour
Add the water, yeast, and sugar to a bowl. Allow it to sit until it
becomes frothy.
Add milk and salt.
Stir in half of the flour so that the mixture becomes creamy.
Add more flour, enough for the mixture to create a soft dough.
Knead the dough on a floured surface for three to five minutes.
Allow the dough to rest for about five minutes.
Divide the dough into six to eight pieces.
Flatten each piece of dough with your hands and then use a floured
rolling pin to roll out each piece. You want the dough to be about
1/4-inch thick.[4]
Heat a grill pan over high heat.
Turn the heat down to low and melt 1/4 cup of butter. Brush the
melted butter over the dough.
Lay the dough face-down in the grill pan and cook for about two to
three minutes or until golden brown.
Flip over and repeat.
If you want to give the flatbread some extra flavor, throw in a dash
of onion salt and a dash of garlic salt
