Hi, dd (12) has food tech tomorrow. They can cook/make whatever they want. However, it has to be done in a 40 minute (a.m) lesson and then p.m they are outside doing games all afternoon - and whatever they have made needs to go with them as they come home straight from games (field is 15 mins from school). They can only make 1 sweet thing (she made biscuits last week) so it has to be savoury. So, need something quick and easy to cook, that a (fairy fussy) 12 year old would eat, and needs to be ok being unrefrigerated for an afternoon. Any ideas? TIA
