Salad or spring onions
Indispensable in the kitchen, and especially in salads.
You won't find the best kind in the supermarket, but if you are near a farm shop, tiny, thin, very young spring onions are delicious served whole with just the root trimmed.
Recipes don't come much more frugal than this cheap and satisfying take on jacket potatoes - ideal food for cash-strapped students and vegetarians.
Anchovies, capers, parsley and olives - plus garlicky mayo - give this bean salad plenty of punch. Chickpeas and haricots verts are a brilliant source of fibre and highly nutritious. Vegetarians could leave out the anchovies.
Low-fat recipes often need quite assertive ingredients in order to give you plenty of taste and flavour: this lovely Japanese-inspired soup is a great example, with shiitake mushrooms adding punch and meaty depth.
This is one of the most popular recipes on the site and is packed with flavour, lifting a simple chicken recipe into the realm of something really special (and easy).
Delia describes this as her favourite vegetarian dish - and it's so versatile we just know you'll make it again and again with whatever vegetables are available.
