Hi Sitona,
Are you really Type 1 and treating your condition with diet only? (as it says in your profile)
There are so many recipes out there on the internet... try any of the supermarkets, for a start. What kind of stuff do you want to eat? What kind of party is it? Most savoury foods are diabetic-friendly as long as you cover the carbohydrate with an appropriate insulin dose.
What kind of foods do you like?
Sam.
