Lightly grease a large baking dish (32cm x 20 cm) with butter, put aside
Place cheese into the TM bowl and chop 6 seconds / speed 8 … put aside
Place basket into TM bowl and weigh in the buckwheat
Remove basket and put into the TM bowl the water, salt and oil
Give basket of buckwheat a quick rinse under water, and then place basket into TM bowl
Cook 10 minutes / 100 / speed 4 (this will not cook buckwheat fully as it will finish off cooking when the pie is in the oven) … put aside in a large mixing bowl
Drain TM bowl … no need to clean it but give it a light rinse with cold water to cool it down
Preheat oven to 180 degrees fan forced and place rack into middle of oven
Add leek, garlic and olive oil to TM bowl and chop 3 seconds / speed 7
Scrape around bowl, cook 5 minutes / Veroma / speed 1 / MC off
Add fresh herbs and 100g spinach and with the aid of the spatula chop 5 seconds / speed 5
Repeat adding 100g spinach x 4 times (to use up the 500g), scraping around sides and chopping with the aid of the spatula 5 seconds / speed 5 until it has all been chopped (after all the spinach has been added you will need to chop a couple of extra times to get it all done)
Add the chopped cheese, zest and juice of the lemon, eggs, feta, and salt and pepper
Mix 30 seconds / interval (kneading button) using spatula to assist in mixing the ingredients
Add spinach mix to the bowl with the buckwheat and stir … keep aside whilst you prepare the filo
Melt butter, unwrap your filo pastry, place on your bench top with a lightly damp tea towel over it to stop it from drying out
On your bread mat (or baking paper) sit your baking dish and determine how wide you need to have your filo so that it extends all the way up the longer sides of your baking dish (this is important so that you are able to trim and roll the edge of the pastry encasing the filling properly), make a mental note of the width you need
Lay down the first sheet of filo, brush quickly and lightly with butter, lay the second piece on top but a little further down allowing for the extra width you need for your baking dish … continue with the third sheet back up over the first sheet, and the fourth sheet back down over the second ... continue laying in this manner using 10 sheets of filo for the base
Lift the 10 layers and place them into your baking dish … position it so that you have an overhang on all sides which you will trim soon
Make your top layer of filo next … continue as you did before brushing 4 sheets of filo with butter but this time laying them directly on top of each other
Pour your filling into the filo base and spread it out so that it is an even thickness
Place the top layer into position before trimming back the edges (I use kitchen food scissors) allowing you enough pastry to roll edges inwards (away from you) around the edges of the pie to create a nice finish
Do a final brush of butter over the rolled edges and lightly in the middle if you have any butter left
Sprinkle the top with seeds of choice
Using a very sharp knife, cut a thin line along the centre of the pie, and then across in three sections so that you have defined serving pieces … this will allow steam to escape during baking creating a lovely crisp crust to the pastry
Bake 50 minutes, turn pie around and bake for a further 10 to 15 minutes until golden
Rest 10 minutes before cutting and serving
Serve with a lovely big garden salad
