@quad I quite like my shrooms.
Onions I tend to struggle with I usually have poree in my freezer atleast.
I can totally understand the problem with "big packages" very well. Especially when cooking for one person.
Atleast I have the "luxury" that I can buy my veggies mostly from nearby farmer (they also have nice fruit and offer shrooms, honey and other stuff from other local farmers). So I can get just as much as I need mostly.
