Erin had her 1st birthday two weeks ago and we had a lunch time bbq.
The kids had home made sausage rolls, (hot dogs rolled in puff pastry and baked in over for 15 mins) We had mini club sammies. with ham, cheese on, home made pizza's , cupcakes which the kids got to decorate just for a bit of messy fun.
we served veges sticks and rice crackers with hummus dip, beetroot dip (called it barbie dip and fooled them all) looks pretty to. tin of drained beetroot and half cup plain yoghurt and blend in processor. and i also made mini hamburger patties which the "boys' barbequed. i also used little cookie cutters and cut shapes out of slices of cheese. all mainly finger foods for the littlies erin munched on a sausage and not much else as she was too busy crawling around everyone and playing out side.
The other idea is to have the children decorate the birthday cake, you pour on icing and provide sprinkles, lollies, licorice, pieces of fruit etc , the kids love this sort of thing.
We just provided a bit of steak, sausages and salad for the adults.
Good Luck. If want recipes or more ideas Pm me, i'll be happy to help
