Here's what I did for my husband's 40th last Jan. Copied from an email I sent to a friend who was hostng a party.
Food - Catered for 30 people. Did two trays of sarnies using two slices loaves - one white, one brown. Roughly two rounds of each type of sarnie. Beef and horseradish; ham and mustard; tuna and cucumber; egg mayo; sliced egg and tomato; smoked salmon and cream cheese; smoked salmon pinwheels; cucumber. Garnished with scattered pomodorino tomatoes and watercress.
Hit Costco for catering packs of snacks -
70? chinese (wontons, mini spring rolls)
72 indian (samosas, pakoras, bhajis)
80 puff pastry bites
80 sausage rolls
48 mini quiches
50 satays
Used half of all the above but all the Indian snacks and 3/4 of satays
One six pack mini Pork Pies, halved
18 cocktail sausages
One bottle sweet chilli dipping sauce
Garlic and onion dip
Tzatziki
Crudites (celery, cucumber, red, orange, yellow peppers, carrot sticks) served on two large plates, each with a bowl of dip in the middle.
1 pack Walkers sweet chilli sensations crisps
1 pack sea salt and cracked black pepper kettle chips
1 pack of 56 cream cake minis - strawberry millefeuille, mini eclairs, hazelnut puffs. Not many people ate these but they looked good and those that ate them had 3/4/5!!! I also had some grapes to put out but forgot.
I've just done my mum's 60th too but I haven't got the details of what I bought for that here. Will try to remember to email them from work tomorrow.
