Holy Moly... you're putting on a lunch at your place for 20 people while you have a toddler & new baby?? You're a better woman than I!!! (should I just call you wonder woman??)

We always have it my IL's place & everyone chips in, although MIL does the majority... she likes it that way LOL We try to help where we can. Everyone brings a meat & possibly a salad. Our luncheon usually consists of...
King Prawns
Oysters
Lobster (every other year)
bread rolls
potato salad (MIL's yummy potato salad!!)
greek salad
Noodle salad (SIL's delicious noodle salad with yummy roast pumpkin in it)
ham
roast pork with apple sauce
roast beef with gravy
roast chicken
Dessert is usually:
pavlova
ice cream
fruit salad
Then we have our coffees, teas, hot chocs with an assortment of chocolates yum yum

We usually then spend a few hours around the pianola but its being fixed atm not sure if it will be back in time

Oh & we open pressies sometime in between pianola songs haha

I love Christmas, its my favourite time of year!

Christmas with my family is pretty similar, meats & salads, not so much the seafood though

A great day with both families (I'm very lucky to have a great IL family)

Good luck wonder woman... I mean pink palace LOL I know you'll do a wonderful job, just dont put too much pressure on yourself!
