In small mixing bowl, stir together milk with vinegar and let sit for about five minutes.

In medium mixing bowl, whisk together flour, salt, baking soda and sugar. With pastry blade, or in food processor, cut butter into flour mixture until mixture appears crumbly.

In small bowl, lightly whisk together milk mixture with egg.

Add wet mixture to dry mixture and stir or process until just combined. Dough will be shaggy (on the wet and gooey side). Add a little more flour if dough appears too wet to form. Stir in cheese, garlic, olives, parsley and basil.

With spatula, add dough evenly to greased skillet. With large knife, score the top like you would cut a pie (see photo). Garnish with a little more parsley and bake for about 30 minutes, until lightly browned on top.
