SHOPPING LIST: Leek, Potato and White Bean Soup (1 portion)
Meal Plan 4, Saturday lunch (vegetarian)

[ ] 1 medium leek (about 150 g once trimmed)
[ ] 150 g potatoes
[ ] 1 tin cannellini beans (400 g). You need half; tonight's stew uses the other half
[ ] Reduced-salt vegetable stock cubes (you need half a cube)
[ ] Olive oil (1 tsp)
[ ] Black pepper

Cupboard check: stock cubes, olive oil and pepper are probably already at home.
Leftovers: half a tin of beans. Keep it in a covered container in the fridge (not in the open tin) for tonight's stew.
