Fish tacos are one of our favorite meals — they’re quick, delicious and most components can be made ahead, making them an easy mid week low-carb meal.

They’re also a great option for dinner parties as you can have bowls of all the different toppings and allow guests to put together their own tacos. The spice mix also works great for chicken or shrimp, or for a vegetarian option use halloumi.

And don’t be put off by the long ingredient list — these healthy low-carb tacos are very easy to put together and require little preparation time.
