Lunch / finger food for 15mo

Ok, so I'm starting to struggle with what to feed DD! I know there are about a million things I could give her but my mind is MIA and I'm struggling to think of some good ideas!!

DD has always been a pretty good eater and I still cook most of her meals but have recently stopped giving her a home cooked meal at lunch time. It's hot and she really should be eating things that she can hold and feed herself with.

She is at day care 3 days a week so I have to careful with what I send for her re allergies - no eggs or nuts. Which sucks because she loves quiches and that is something she can hold/eat herself. Oh well.... so I have been sending an assortment of food such as sandwiches, fruit (mainly banana's or pear), home made banana muffins, cubed cheese etc. But I feel like I'm sending the same things every day and I want to give her more of a variety of foods to eat. But what??

If anyone has any lunch box suggestions for a 15 month old it would be greatly appreciated!

Thanks,
Fi
