I have a nice, hearty cheap recipe to add.
Pinto Bean Soup:
500g = 85p and makes 8 adult portions.
for 4 servings use half a bag
soak beans overnight in cold water.
Next day:
Drain beans, add 8 cups (2 Liters) of water and cook until soft (usually about 1.5 hours)
Season with salt and pepper and serve. ( do not add the salt in the beginning as the beans won't go soft).
A variation is to start with a chopped onion, slightly sauteed before cooking the beans.
Just a thought, I notice you do not have alot of wholemeal items, i.e. brown rice etc. what do you use instead?
