Roughly chop the tomato, cut the
cucumber into sticks and split and
stone the olives (if using).
Now heat the tortillas. If you have gas,
put each one for 10 seconds on a lit gas
ring - you have to be a little bit brave -
then turn it over quickly, using tongs, and
heat the other side for another 8 seconds
or so. The tortillas will be slightly charred
in places, which adds a fantastic flavour. If
you don't have gas, warm a pan to a
medium heat before quickly tossing in
your tortillas one at a time. You don't need
to have any oil on the pan.
Make a row of tomato, cucumber, feta
and olives down the centre of each warm
tortilla. Now spread the houmous around
the top and sides of the tortilla. Fold in the
sides to seal in the ingredients and roll up
tightly to make a big cigar. Cut in half and
eat with your fingers.
