So no, doesn't really work well as a word for foodstuffs.
Yeah, but peat isn't something you'd want to eat. Its amazing to smoke whisky in, though.
But, if you want to 'veganize' those meatballs, mushroom is a common savoury alternative, I'm told a lot of the impossible burger type ventures are opting on PEA protein: so may just name them PEAballs?
I worked at a Vegan/vegetarian place for 1/2 year just to get more rounded before I went off to Michelin star stuff, and its rather labour intensive to make this stuff just taste 1/4 as good as meat.
So my question was always: why not just serve better quality, locally sourced, organic/grass fed beef? And just eat less of it; a 50/50 mixture of beef to mushroom yields an amazing juicy, umami filled burger.
Side note: I propose that vegan meatballs be called peatballs! (Peat is made out of plants, correct? I'm not super knowledgable about that stuff.)
