Think these are technically called Quesadillas....
 
Per person-
 
2 tortillas and whatever you fancy left over.
 
Spread one tortilla with a tablespoon of guacamole, a sprinkling of tomato salsa, loads of grated cheese and maybe a tiny bit of sour cream.  If we've run out of that, natural greek yoghurt tastes as good.
 
Put the other tortilla on top of the other in a sandwhich and fry in a VERY lightly oiled frying pan until brown and crisp on both sides.
 
Cool a little and cut into wedges.
