- 200 g potatoes (baked or boiled)

Method
- Cut the potatoes into chunks and boil in salted water for 15 to 18 minutes. Add the cauliflower florets for the last six minutes.

What this plate gives you
Cod is about 23 g of protein per 100 g cooked for almost no fat, so 160 g of it gives 37 g of the 45 g of protein and the whole plate is 10 g of fat, most of it the butter. At 478 calories it is a little under a quarter of a 2,000-calorie day; the potatoes and cauliflower are the 53 g of carbohydrate and the 8 g of fibre. Roast the cauliflower in florets rather than boil it; it browns and tastes of something.
Swaps
- Haddock or pollock: the same numbers.
- Olive oil for the butter: the same calories.
- Capers and parsley in the butter: no change to the numbers.
Keeping it
Cooked cod keeps three to four days in the fridge and is better cold than reheated. The vegetables reheat.
