Tomato & thyme cod. Just made this - delicious! I added quite a few whole pitted black olives. Served with steamed baby new potatoes dressed with garlic butter, and some salad leaves and red onion in a balsamic and olive oil dressing.
I love cooking fish in a foil bag and have been doing it for years. It's a great way of cooking – it's healthy and, by keeping everything in a little bag, the flavours are beautifully intense. You can prep this in advance – but don't forget to write your loved one a little message, plus some cooking instructions, and attach it to the foil. A lovely thing to find waiting for you in the fridge.
