Here you go:
2 cups SR flour
pinch salt
3/4 cup milk
1 tab butter

(I use powdered milk - about a tablespoon and use 3/4 cup water)
Rub butter into flour (and milk powder if you use that) and salt
Cut in milk until a smooth consistency.

Then I just roll out into a rectangle, add my toppings, roll up and slice and put onto tray. I usually sprinkle a bit of extra cheese over the top before baking.
