One of my current favourite supermarket buys is mackerel fillets. I am thankful that Iceland has frozen fillets for £4 for a pack of 5 or you can buy 3 packs of frozen fish for £10. It’s a brilliant buy because fish is always healthy. This isn’t an advert for Iceland mind you. I thought it would be nice to share my supermarket find! I used to poo-poo buying things from Iceland but now that they’ve expanded their offerings and the food range is so much better, I always go by Iceland to see what I can get!
Back to the fish, a quick way of prepping the fish is to rub olive oil over the frozen fillet, salt and pepper it and grill for 7 minutes on each side. I usually have the fish with leftover roasted veg and sometimes, when I want some carbs, I have a few pieces of baby new potatoes (also roasted!).
