The much-maligned and underrated sibling of the meat pie, the pastie is in my opinion superior in most every way. Unlike the pie, traditionally contains actual vegetables so is therefore rather healthy.

Pascal = P = patch

pastie /pay'stee/ n.

An adhesive-backed label designed to be attached to a key on a keyboard to indicate some non-standard character which can be accessed through that key. Pasties are likely to be used in APL environments, where almost every key is associated with a special character. A pastie on the R key, for example, might remind the user that it is used to generate the rho character. The term properly refers to nipple-concealing devices formerly worn by strippers in concession to indecent-exposure laws; compare tits on a keyboard.

To make a pastie:

Take some pastry: flaky pastry, filo pastry and puff pastry will work ok. Roll it out thin, and cut it into circles with a diameter of around 20 - 30 cm.

Prepare your filling. This can be anything from cooked vegetables which are cut up small, to cheese and bacon .

Place filling on one half of each circle, leaving a bit of room around the edge. Beat an egg, and brush exposed edges with egg (using it like glue). Fold the pastry in half over the filling. Press the edges down with a fork to seal them. The pastie should look like a bulky semi-circle. Brush last of egg lightly over top of pastie, and bake it in the oven until the pastry is brown.
