Heat oven to 400. crumble the feta cheese and mix in the parsley, stir to combine and break feta into smaller chunks. Start with good fresh or frozen phyllo. the key is to purchase it at a place which sells a lot, so you know it is fresh. Take a sheet of dough and brush with butter. Place 2 tbsp of the cheese lixture along the bottom of one of the short sides. Don't pull the filling too close to the edges or it will seep out the sides. Fold the long edges of the dough in about 2 inches on each side. Flatten and dols the short end of the dough over the top of the fillinbg. Roll up to give a tube effect, then brush with butter and place on greased sheet. Continue using each sheet of dough and 2 tbsp filling. Bake for 10 minutes at 4oo. serve warm from the oven.
Feta is a salty hard cheese sold in many packs. My friend uses vacuum wrapped ones in a little brine, and sometimes chunks in a tube of brine.If you only see other types, you can soak it in a covered bowl of water to release some of the salt.
