I lived for 2 years in the UK - I didn't understand how they could eat that stuff ... it literally has no taste. Moved back home for 3 years and now I'm living in the Netherlands for the past year .. it tastes like nothing, the tomatoes, the cabbage, the carrots .. the parsley .. they all are so bland. We found some actual farms around that we got some actually tasty stuff during season .. but the stuff in the supermarkets tastes like grass.
