Most of the foods I keep are unprocessed, and much cheaper than the processed stuff.
Oats (not pre-cooked)
Milk (always full cream)
Double Cream Greek yoghurt
Whatever fruit I can find
Lunch and Supper stuff
lentils (which become sprouts)
potatoes and/or sweet potatoes
cashew nuts and/or pumpkin seeds and/or sesame seeds
Two other Veggies (like carrots, peppers, cabbage, broccoli, marrows, butternut … blah)
Other stuff I sometimes have
meat, fish, chicken
canned tuna, muscles, oysters, canned beans (for when I’m absolutely beyond lazy) – These are not good by the way, too much salt, and I think some other monstrous preservatives.
wraps (for when I’m very lazy too)
Some kind of cheese, preferably brie
