2 x mackerel fillets
Few sprigs of rosemary
Salt & black pepper
Cheesy potato wedges
1. Heat some olive oil in a frying pan & add the mackerel fillets, seasoning with salt & pepper.
2. Cook on medium heat for about 15 minutes, turning occasionally, until browned & cooked through.
4. Add a knob of butter to the pan, which will still be hot enough to melt the butter without burning it. Once butter has melted, add as much lemon juice & rosemary as you like & stir well, then pour over the fish.
