What I think about when I shop for groceries? It’s usually not what I want to eat but how I can pack more proteins, vegetables and colours into a few meals. I decide what to do with my purchases only later. The problem with planning a menu is planning. There isn’t always time for that, yet not spending time to condense the shopping list only creates wastage.
That is why I only think about how many meals I’m buying for, and then I pick different items from different food categories until I have enough. I usually buy for two days, and each time I put a rainbow into my basket, say a carrot, burdock and cabbage, or a capsicum, eggplant and bak choy. I try not to repeat these within the next two market visits, because the best diet includes everything.
