This is how I always make my salmon.
1/2 teaspoon of olive oil on each 120g fillet, freshly crushed black pepper, finely chopped garlic and a sprinkling of sea salt. Comes in at 270 calories per fillet. It is very easy and no fuss to make and just bung it in the oven.
Served with Jersey royals and green beans or other purple sprouting broccoli and/or salad. My meal tonight was 680 cals.
