Main course (lunch) for 20

[Lysianthus]

Please could I have suggestions! It's for a lunch club for seniors, so I need to avoid curries/spice etc and I can't use onions.
I've exhausted the sausages, cottage pies and roast ham, so looking for ideas which I can prepare at home and which won't cost the earth. TIA.

Jacket potatoes and salad
Hot pot of some sort
Fish pie

Meat pie
Stew and dumplings

Stew, lasagne, hot pot, casserole?

Baked chicken pieces. You can put them in one or two v large baking tray super snugly with flavouring /marinade of choice and cook on 150 fan or 170 normal for 45 minutes, baste, then another 20-25 minutes. Come out beautifully.

Serve with mashed potatoes or new potatoes and mixed greens.

When you say seniors, how old are they, and do they have any health issues, e.g. arthritic hands, swallowing problems, that might make it difficult to cut food up? If that's the case I'd avoid anything that's on the bone.

Cod or other white fish - fillets, cut into halves or thirds if they're large. Bake until just cooked in cheese sauce or parsley sauce. Serve with new potatoes or mashed potatoes or if you have the time and urge to be fancy, duchesse potatoes, plus a green vegetable, e.g. peas or green beans or broccoli.

Big sausage plait.(sliced) . Boiled new potatoes, baked beans or peas and beans.

An oven baked risotto

Fish pie. You could use frozen supermarket fish to keep costs down.

Would a very mild chilli con carne be too spicy?

Quiche, salad, chips
Fish and chips
Steak pie, potatoes and veg
Chicken casserole, mash and veg
Beef stroganoff with rice
Salmon fillets with new potatoes and veg
Mild curry and rice, poppadoms, mango chutney
Sausage, apple and potato pie with green beans

Fish fingers and chips.

Chicken pie with either mushrooms or broccoli?
Or to save having to make pastry, chicken casserole? Nice if you put in some chopped dried apricots too.

Have you asked them for suggestions?

(Mil used to go to a lunch club and there were a couple of people there who would complain, no matter what food they were given).

Lasagne could work, in various forms. Also chicken pieces in a Dijon mustard/cream sauce. I would browse the COOK website and see what you might be able to recreate.

If it doesn’t have to be hot, how about coronation chicken? Curry powder I know, but sufficiently British to hopefully go down ok. Serve with rice salad, green salad and crusty bread.

Roast ham, but with cauliflower cheese instead of eg potatoes?

My grandmother also loves beef/mushroom stroganoff, but that’s tricky without onions.

pulled bbq pork/ beef/chicken.
can have with rolls, jackets, new potatoes, roast potatoes, salad

if bbq is too controversial you can do it as a beef brisket stew

My fil is a senior who likes non spicy food. The most exotic thing he eats is pizza. Anyway, I’d say roast chicken thigh, mash and gravy with veg. Or chicken pie, mash and veg. Gammon, egg and chips?

Don't see how the OP could make a stew or lasagne without using onions?

Macaroni cheese

Toad in the hole
Lasagna
Fish pie
Quiche

Vegetable and bean casserole, you could add dumplings or serve with a scone. very economical.

Macaroni, cauliflower and broccoli cheese bake. You could add leeks to this if they are acceptable, also diced ham or sliced sausage.

Cassoulet, an economic version with boiling sausage, pie pork or diced bacon, tomatoes & beans.

Hearty Minestrone soup with pasta and beans.

NO ONIONS!!

She could just leave the ONIONS out.

Cauliflower cheese, boiled new potatoes, sausage.

Why do you need to avoid spice ?

Big quiches and salads are good

Lasagne's

Tuna pasta bake

Shepherds pies are easy

Not sure what form your sausages took previously but a sausage casserole could work.
Or pork a pork casserole with leeks, apple, parsnips and cider.
Chicken and bacon bake (mashed potato top)

A couple or 3 Huge gammons are incredibly easy to prepare, easy to serve, and they will like it.
