Vegetarian toddler tea with vegan options?!

[Poofus]

I need some bright ideas for a 3rd birthday party cold buffet tea, please, for vegetarians plus two vegan children. I had planned on cheese/egg sandwiches but that won't work with vegans. Peanut butter might be a sandwich option but I'm nervous about possible allergies (though surely the parents would have warned me?). Pizza slices are obviously out and most vegetarian sausages have egg/milk in them... What else could I do? I'm beginning to panic!

How about some falafel balls in mini pitas?
Carrot and cucumber sticks with humous
nut butter sandwiches on wholemeal bread or those veg spreads in a tube (nicer than they sound) that you get from Holland and Barrett
Ready salted crisps, pom bears, apple slices

I wouldn't worry much about them having a balanced diet so long as there is something they'll enjoy to nibble on at the party.

Humous and grated carrot sandwiches. Roasted veg pittas. Guacamole and carrots/peppers/cucumbers to dip. Fruit kebabs (not cooked - just chopped fruit eg pineapple, apples, grapes, mango, melon etc) threaded onto kebab sticks.

Oops just seen that it's for young kids. Ok, lose the kebab idea but little bowls of cut up tropical fruit would surely go down well. Papaya in particular is lovely and most kids seem to like it.

Humous and guacamole with pitta bread slices/ carrot sticks/ cucumber

Falafel

Strawberries/ grapes/ melon/ bananas

Vegan cake/ brownies - recipes online but many basically replace egg with mashed banana, and use vegan butter. Brownies work best as no need to rise.

Cookies - vegan butter replacement.

Kids at 3 years mainly want balloons and party games so wouldn't worry too much. Mine would eat all of above happily though and is same age

Thank you so much! Some great ideas here. Falafel would be good, and fruit pieces will definitely work. Hummous and veg to dip in sound perfect too. Bloody pom bears are not vegan, sadly, but hula hoops seem to be so they're on the list. Thank you again. :)

Sausage rolls are dead easy. Lots of readymade pastry is vegan and you can buy a dry packet blend of vege saus mix from most supermarkets et voila.

Cous cous and roasted veg salad

There are vegan pestos too (sacla do a roasted Aubergine one that's got no dairy in) so you could do a pasta salad or spread it on a flat bread and make a garlicky pizza style bread.
