this is a great dish to make while courgettes are still in season and full of flavour, especially if you’re lucky enough to be growing your own and able to eat them when they are freshly picked (people always talk about a freshly picked tomato having more flavour than those you can buy, for me it is courgettes that most repay your home-gardening efforts).
the courgettes are the star of the dish, sautéed in butter until they start to turn golden. they also soak up the porky goodness of pancetta (if you want to keep this veggie i think sundried tomatoes can do a similar job) and i added a little garlic and chilli as well.
the genius ingredient, which gets everything to work together, is capers. lemon is my default choice when i want something sharp or fresh in a dish, but the salty capers give a more subtle tang which, i think, works particularly well with butteriness of the rest of the dish. parsley and basil to finish.
