My basic vegan list (apart from things I grow):
Porridge oats
Sultanas
Apples
White (or red) cabbage
Frozen vegetables - including those handy baked potatoes from Iceland
Nutritional yeast flakes
Tinned chickpeas, lentils, coconut cream and tomatoes
Gram flour
Rice
Pasta made from lentils and/or peas
Marmite
Peanut butter (by the tubful)
Yorkshire tea and coffee
Cacao nibs (for those peanut flapjacks)
Olive oil
Oat milk
(and all the spices, condiments etc. I enjoy)
I can always rustle up some soup, chick pea curry, broccoli mash and home made biscuits at short notice - all welcome in this chilly weather.
