Easy but impressive dish for 12?

[midori1999]

It will be a casual thing, but a proper meal is needed.

I was thinking a fish pie and then some steamed veg, plus another dish that could be served with the steamed veg, but not cottage pie andprobably not a stew/casserole type thing, but I can't think of anything?

Lasagne
Mac cheese
Hotpot

How about a chilli?, serve with lots of sides: guacamole, tacos, grated cheese salsa, salad, sour cream torillas etc?

Oops, I misread your post.What about a meat loaf, or nut roast for veggies?

How about a big savoury tart? Goats cheese and caramelised red onion is a great combination, or roasted veg + parma ham....lots of possibilities. You could buy the pastry base ready made and just do the filling yourself.

Slow roast lamb shoulder or pork belly? Might be a bit heavy alongside fish pie.

Out of interest : why two big dishes, why not just one (fish pie) with your side dish? For 12 I would not feel the need to do a selection.
