Here’s where I start guessing about measures:
This is a pie crust. Trust me. Put the shortening in the mixing bowl first, and slowly add the flour until you’ve worked it all in, and you’ve got a pile of small greasy lumps. Add the water half at a time and mix until you can’t. Then squish with your hands until you get a ball of dough and there’s no loose flour in the bottom of the bowl. Split the ball in roughly half and roll out the slightly larger half on flour-sprinkled parchment paper until it’s about 4cm bigger than your pie pan. Flip that thing into the pie pan, punch some holes in the bottom with a fork, and bake @ 180C/350F for about ten minutes. While it’s baking, roll out the other half the dough to about the size of your pie pan and leave it.
Microwave the broccoli for ~6m, until it stops being frozen. Mix the spice and flour into the cheese. Put half the onion into the bottom of the pie crust, then add broccoli, then add the other half the onion. Fill in the gaps with cheese. Put the top crust on and fold the edges under, pressing them with a fork. Bake at @ 180C/350F for ~30m. TADA! It’s a pie.
