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.

Just starting Keto, love the fish taco recipe. Am trying tilo figure out how keto and Atkins measure up.  I lean vegetarian, so alot of the keto is too heavy and not animal friendly.  I do eat fish and eggs.
I am exhausted with cooking .

I get that! Some of keto recipes tend to be a bit fatty/greasy (which is ok but might not be what you want). Think of fat as "filler". You don't have to add fat to any meals (extra oil or using fatty meats is not necessary). Protein is far more important, unless you are doing it for therapeutic reasons in which case high-fat is better.
