I do a lot with taioba (https://www.worldfarmers.org/crops/taioba/ ) which is similar and is a very large and insistent weed in my garden. Very spinach-like but also very high levels of oxalic acid, so can`t be eaten raw. I think the best thing I've done was an omelet layered with the leaves.
These leaves are also good for things like baking bread on top of (instead of using parchment paper) or using underneath steamed bread/buns so they don't stick to the steamer.
The only cure for that is hours of television radiation. And this tiny ad:
