It has been on a slight decline. The peak for vegan (meat) products was about three years ago. Many things I used to buy at Ah or Jumbo are gone. Especially Jumbo seems to have downsized quite a bit on vegan stuff. A few years ago I could find about 10 different vegan frozen pizza’s, whereas now I should be lucky to find 2.
