A brilliant, warming 30-minute traybake, all in one tin. I love the combination of roast sweet potatoes with crumbled feta and a bright, fresh pesto; adding butter beans to the mix brings another hit of protein, as well as getting more legumes into your diet – win-win! A jar or tin of chickpeas would work just as well, if that’s what you have in, and feel free to substitute the parsley for other soft herbs, should you wish.
