Skinny Tuna Noodle Casserole is a delightful dish that marries comfort with a lighter twist. This hearty recipe features tender egg noodles generously mixed with flaked tuna, fresh peas, and a medley of vegetables, all enveloped in a creamy, yet low-calorie, sauce made from Greek yoghurt and a hint of Dijon mustard. Topped with a sprinkling of wholegrain breadcrumbs for a satisfying crunch, the casserole is then baked to golden perfection. Perfect for those chilly evenings, this dish not only satisfies the soul but also keeps the waistline in check, making it a favourite in many British households. Serve it alongside a crisp green salad for a complete meal that is both nourishing and comforting.
