Probably a bit late but I just found this thread.
Some of those veggies seem to cry, to me, for a ratatioulle. A dish I always wing with what we have on hand.
Or get some smoked pork hocks and make a soup/stew, kind of a caldo gallego thing which, loosely translated, I think means add good veggies and some pork to a pot and enjoy. You can always add some pasta, would not hurt, or dumplings.
Perhaps a frittata, one of my favorites.
For just good eating take the cooked potatoes, mash them, and form them into patties.
Then saute; the mashed potato has not seen a better use, IMHO.
Or add some flour and egg and make potato pancakes (I usually make mine with raw taters, but cooked would easily work).
Daikon radish, hmmm, how about a slaw? Add some grated carrot for both flavor and color, whatever else you might like, and a dressing.
Can always make a tomato based sauce with almost any veggie.
If the veggie cuts are big enough, could do a tempura. Have not done one in years but always enjoyed the stuff.
Sounds like you have a goldmine of veggies. Enjoy.
