5. Then there's tofu by-products! Stuff that comes from the yuba, the 'skin' that gets skimmed when you boil soy milk..
You can get it frozen like this https://www.sayweee.com/en/product/J-Y-Fresh-Beancurd-Skin--Frozen-1/57130?trace_id=395d0b05-98c4-450b-b469-79a3b3f32475
It can come stuffed with pork or fish (yuba dumpling type things are very common)
Fresh if you live near a tofu factory or make it yourself
It can come fried, like tofu chips
You can get it in sheets, that you can then cut into noodles
