Smoky spiced white fish baked in 12 minutes, tucked into warm corn tortillas with a crunchy lime and yogurt cabbage slaw and avocado. All the flavour of fried fish tacos with a fraction of the oil, and 29g of protein a serving.

Two tacos have about 29g of protein and 8g of fibre for 341 calories, including the tortillas, slaw and avocado. White fish such as cod, haddock and pollock has about 1g of fat or less per 100g, so most of the fat comes from the avocado.
Baked, not battered. Fish tacos from a taco stand are usually battered and deep-fried. A spice rub and a hot oven give plenty of flavour with one tablespoon of oil for four people.
Why corn tortillas. Small corn tortillas are the traditional choice in Mexico. They are naturally gluten-free, smaller than most flour wraps and a source of fibre. Check the pack if you need them to be strictly gluten-free, as some are made with a little wheat.
The slaw does the work of sour cream. Red cabbage and carrot in a lime and Greek yogurt dressing add crunch, freshness and fibre with very little fat.
Fish guidance. In the UK, the advice is at least two portions of fish a week, one of them oily; US guidelines suggest at least 8oz (about 225g) of seafood a week for adults. Cod, haddock and pollock are low in mercury. For another white fish dinner, try the lemon and dill fish parcels, or for vegan tacos, the sweet potato and black bean tacos.
