classy?
halved cobs/rolls with grated cheese/ plastic ham are out then?
cold rice and veg,
cold pasta with tuna sweetcorn and mayo,
you could make a kids birthday party style buffet but put everything in nicer bowls,, its all about the presentation anyway!
chicken legs, pineapple onions and cheese
bread sticks and dips, cvashew nuts, mixed indain snacks, spring rolls,,
if you can serve anything hot, try garlic mushrooms,
cold mini pizza,
try and find some vegetarian party snacks in your supermarket freezers, they area bit different and really go down well. they have sausage rolls but wth mushy veg stuff in them!, an you can never go wrong with a massive pork pie cut into tiny pieces... my favorite..
for the dessert, dont try and get loads of different puddings, try just two.. dont get all the mini cakes, look at all of your options and think which would i eat if i was a guest, its easy to blag the savories, but the cakes are easy to spot the cheap ones, try a supermarket finest range of fresh cream cakes if you are only having a few guests, if you are talking 20 to 100's of guests, try and find a local catering supplyer of cakes, most do cheesecakes and chocolate fudge cakes, and both will be made quite nicely, "straight out of the box and a bit different"
or if you are making your own puddings,
id start off with mini banoffee pie,s, and the tartlets mentioned above..
