I was so knackered yesterday, after a strange headachy, virussy thing over the weekend. All I wanted, in the middle of this crazy wet and miserable July, was soup for my tea. And I didn't want to spend long making it. Thank heavens for for the frozen pea, surely the cook's best friend? Ridiculously simple: sweat an onion in a good knob of butter, then add a big bag of peas (450g / 1lb), just cover with Marigold stock, simmer for 10 minutes then blitz with a hand blender into a soup of verdant freshness. Season with loads of black pepper, some mint if you like, and stir through some chopped ham (I had some leftovers from a gammon joint at the weekend). Served with toasted cheese sandwiches, it was heavenly comfort food in 20 minutes. Rubbish photo, I know. Definitely an under a fiver job.
