It looks like this.
It's got a pretty strong taste and it is often used in salads to enhance the flavour.
It actually has like 5 times more minerals and vitamins than the fully grown plant.
My favourite one is heartburn (the main ingredient of mustard), but it's got pretty strong taste, so not everyone would like it.
Interesting! Looks like cress (peppergrass).
I think I’ve never tried it. If I had more time, I’d love to cultivate salad and other vegetables on my own. Self-made is the best quality one may get :)
