This weather is crazy. Just when you think it’s time to live on watermelon and salad in your flipflops, hailstones the size of conkers start smashing up your greenhouse. It’s important to be prepared for all eventualities and this includes having comfort food and a slanket to hand. This lasagne is easy to make, fools small children into eating vegetables and is perfect for sub-zero summer afternoons. I used Highcross from Wildes Cheese which is matured in a vat of salt, water and lemon. It’s salty and crumbly, a bit like Feta and its sharpness goes well against the sweet squash.
