Meat dish and a veggie dish that can be scaled up for about 30 people total

[spub]

I'd be very grateful for any suggestions. Having about 30 people round following ds' birthday party which I've had the sense to be holding elsewhere!
There will be a combination of adults, kids, veggies and carnivores.
In the past I've made the Jamie Oliver mozarella pasta bake from Jamie's Italy and Nigella's chorizo chilli and they have worked well but I'm bored of those and think I'd like to try other dishes that would scale up and are relatively straightforward to prepare.
Any ideas very welcome!

coq au vin
spag bol
hungarian goulash
ratatoullie
chick pea curry
meat curry

I would cheat and do chilli and jacket pots.

Veggie mince and beef mince

You could put out some salad bits to go with the jacket pots.

I'd do a buffet of things which can be prepared in advance and are nice at room temperature:

Panzanella
mozarella tomato salad with pesto
meatballs
a nice salad with carbs (rice salad, couscous salad)
Charcuterie
bread basket
roasted veg
