Help I need light lunch ideas minus the cooking for after a christening in a park

[Miss K]

Ok so we are going straight from the christening to the park will have a bbq but don't want to do a big BBQ just a light lunch with some savoury snacks no cooking needed.

We will do a sausage sizzle but what else???

I am usuall good at this but we are doing it on a budget now!

I should add I will cook day before but not on the day ideas LMAO I am soo not thinking right now I am in panic mode!
