Interesting idea. Your freezer is definitely your friend if you're using small quantities - you can buy bags of frozen berries and veg and of course freeze any surplus from fresh produce. Then it's easy to add say a handful of berries to milk-free overnight oats or bircher muesli. Soups are a really good way of getting variety in too. Let's see, how was this week...
Rice would be definite no after 4 days in the fridge but you could try rice noodles or couscous, both of which only need a few minutes in boiling water. My go to work lunch used to be a pot with ready to wok noodles, frozen veg, 2tsp miso paste, dried seaweed and frozen gyoza - take out of freezer into fridge overnight, pour boiling water on at lunch and microwave for 4 minutes. Supermarket packaged pre-cooked grain pouches might work too though the cost and waste always puts me off!
Let me see, how has the week been.
