This is still slightly a work in progress, so no photos - they didn't really work tonight! I know what I did wrong - I added all the water at once, as I would had I been going to make the dough in a bread machine, when really, I should have added it bit by bit.
1/2 packet (250 g) cheese and onion bread mix
up to 160 ml warm water
Put the bread mix into a bowl and add the water, working it all the time (a hand mixer with dough hooks is a plan, or use the dough hook on your food processor, if it has one, but you can do it by hand if you wish) until it is smooth and non-sticky. Let it sit for about 30 minutes, until it has risen a bit.
Knock it back, and roll it out as thin as possible on a floured board. Cut in half (or thirds, or quarters, but this amount is ideal for two) and heat a little sunflower oil in a frying pan. Add the flat bread and cook for a minute or two on each side, as hot as possible. Then cook the second/subsequent ones in the same way. Serve at once.
