Things are as you expect, Our beans are in the bottom right absolutely chilling as kings.
Grains are “better” than I would have expected.
I so wish we could get actual wheat grains at the supermarket, possibly bio. Instead whole cereals are mostly sold as animal feed (so with fewer safety standards). It’s bs. Same goes for soy beans! They give 'em out to farmers for a lot less than a 1€/kg as animal feed, but I have to order them online? While every corner shop has tofu, soy milk, etc… come on 😅
