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.
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.
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.
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.
Recipes don't come much more frugal than this cheap and satisfying take on jacket potatoes - ideal food for cash-strapped students and vegetarians.
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).
