bacon and sausages
It is actually illegal to import uncanned meat so be careful you don't get caught, I know a lot of people do it and I have never heard of a problem but you should be aware.
My wife for the kids normally takes a pack of dairylea triangles, a couple of tins of tuna and a couple of tins of ham however this year with the reduced luggage allowance the tins are going but the youngest must have her triangles.
We shop for fresh bread most days, not from the supermarkets but direct from the bakers. We buy salamis and salad from Tansas also the Jam overthere is the best I have ever tasted and thats lovely on fresh bread with a bit of butter.
I am sure you will cope, also if on a budget try the Pide shops for a kabab or turkish pizza they are good value at lunch, also we occassionaly go to Harry Rams the odd evening where Pie and chips and a drink for 4 people was about 40 Lira last year which is a cheap meal.
