@TheBreadmonkey include CARROT SOUFFLÉS!! The most delicious thing. (I add apples, too) pus the other savory suggestions.

@TheBreadmonkey it's a bit unconventional, but hear me out ...

You could make potato gnocchi (mash potato mixed with flour to form dough, rolled into shapes and boiled) with a curry sauce. Carrot puree can be used as a base for curry paste instead of tomato. The onion, parsnips, and sprouts can be added to the sauce or served on the side (char grilled is best)

@TheBreadmonkey Potatoes, onions, carrots (why not?)... Got any tinned or bottled chestnuts? Apple juice or cider?

Bake in the oven for for a veggie Himmel und Erde. S'very good.

Sprout are perfect just lightly boiled, wiv salt an' pepper and whatever you use as a butter substitute.

Parsnips were invented by the Devil.

@TheBreadmonkey Looks like you have yourself some bubble and squeak! (Or maybe just a casserole if you have some tinned tomatoes and crusty bread?)

@TheBreadmonkey

Make bubble and squeak with the potatoes, onions and sprouts. Roast the carrots and parsnips

@TheBreadmonkey Just par boil everything then roast them with some herbs. Champagne and roast potatoes are a winning combination b

@TheBreadmonkey parboil the potatoes, chop & fry all the veg gently so they don't brown or burn, until quite soft. In batches if necessary. (basically a mirepoix https://en.wikipedia.org/wiki/Mirepoix ). Perhaps steam the brussels sprouts separately. If you have any garlic or other suitable herbs they would go well in it too. Then make up a saucepan of gravy and serve the veg with that.

@TheBreadmonkey I'm assuming your cheese grater crisis is now well under control so you can grate these vegetables should you choose that route? #BensCheeseGrater

@TheBreadmonkey minestrone?

@TheBreadmonkey Cornish pasties?

@TheBreadmonkey chip them, steam them, oven fry them, serve with garlicky hummus

@TheBreadmonkey Potato and parsnip latkes - delicious. Magazine https://share.google/zbLRFZibWoNwfXEDh

They're great with applesauce if you have! You can do without the eggs if you're making these vegan, of course.

@TheBreadmonkey

vegetarian goulash.

@TheBreadmonkey
With some more ingredients maybe you can prepare some baked vegetables quiche.

@TheBreadmonkey Maybe for the carrots you can do this salad?

@TheBreadmonkey Raw carrots make for good finger food when quartered long-wise (cut to whatever length feels right)

@TheBreadmonkey prefacing by saying this is a complete faff, but lean into the Stranger Things theme and go 80s Americana-style finger food: potatoes and parsnips and carrots into fries-type-things, onions into onion rings, sprouts, um, probably roast, but then stick 'em on cocktail sticks. Provide much ketchup and "ranch" (whatever that is) and some kind of melted cheesy something and hummus and salsa and guac, to dip them all into. Arrange in the shape of a demogorgon.

@TheBreadmonkey

Christmas wedges.... par boil some potatoes cut into large wedges.

Season and roast in the oven along with some carrots and parsnips... until nice and crispy, cook up some diced bacon and sausages... wrap the sausages in bacon and slice after if you prefer... make some stuffing. Fry of some diced onion.

Assemble in a bowl and smother in a nice gravy.

@TheBreadmonkey

Pot pie with creamy sauce (parsnips, potatoes, carrots and onion, plus chickpeas, and green peas if you have some in the freezer).

Brussels sprouts salad: shred them, toss with a sweet mustard dressing, and top with toasted nuts.

The curries people have suggested sound good too.

@TheBreadmonkey Grate the vegetables and make latkes! Except the sprouts, I see no way outta roasting those.

@TheBreadmonkey roast veggies with spices. Just chop up smallish, oil, cumin or garam masala, chilli. Bake. I'd normally do it as a side to something else. Might be a bit dry on its own?

@TheBreadmonkey maybe dosa or potato pancakes

@TheBreadmonkey Maybe onion rings, french fries, and parsnip chips? Deep fried food is great for parties, and home-made is always better.

@TheBreadmonkey A couple of curries? If you have some chick pea flour you can make bhajis with the onions and/or the sprouts as well.

@TheBreadmonkey Baby, you've got a stew going! https://youtu.be/Sr2PlqXw03Y?si=wk10--Q1-gK-d6Ta

@TheBreadmonkey Katsu curry.

@TheBreadmonkey Some kind of veggie pie? A nice shortcrust pastry and a creamy sauce (vegan, obvs).
