There are various recipes floating around on diet forums, but this is the one I used:
Makes 8 scones:

Ingredients : 
1 packet of dried potato (eg ‘Smash’- although I made this with an Italian version as we were away staying with family)
3 eggs
1 tub low fat cottage cheese
sprinkle of chilli flakes (to taste)
1 cal spray oil


Pre-heat oven to 180 degrees
Beat the eggs in a bowl.
Mix in the tub of cottage cheese and sprinkle in around a tsp of chilli flakes
Add the packet of dried potato and mix.
At this stage you should have a ‘dough’ that is slightly wet but mouldable. I had to actually add another 1/4 of a packet of potato as my mix was too wet – unfortunately my recipe didn’t have weights, so it could be that the Italian mix was a smaller packet that British/US mixes.
Gather the dough and portion in to 8 equal pieces.
Shape into ‘scone’ shapes – I made mine 1.5 inches thick.
(you could flatten the dough out and cut out using cutters, but we didn’t have any as we were on holiday, and this method worked just fine).
Spray a baking tray with spray oil
Put ‘scones’ onto the tray, and bake in the oven for around 15-20 mins, or until golden brown.
Allow to cool.
