Turnips can be subbed for potatoes in soups and stews, but so can radishes.
Radishes can also be used to make a really good faux-tato salad. Boiled, chopped eggs, pickle relish, minced onion, mayo and a bit of mustard added to steamed or braised radishes (well drained and patted dry), dash of cayenne, salt and pepper.

Don’t toss them radish greens either, but they have to be used fast.
I love radishes, when you are on a submarine the 1st thing to go is fresh veg, but we would grow them onboard.
So good 3 months out to sea...
