    We love a good taco, c’mon who doesn’t? These Keto Fish Tacos are beyond good.  We don’t want to toot our own horn, but these are seriously among the top 5 best fish tacos we’ve ever eaten, and we’ve eaten a lot of tacos.  The seasoning of the fish and the salsa, THE SALSA, really are what take this taco recipe from ordinary to extraordinary.

    We wanted to share this recipe with you guys without adding to the carb count so we served it on a bed of butter lettuce, however, if you want to make this a more traditional taco, check out this keto tortilla recipe (only 2 net carbs) and ready in 15 minutes!

      You gotta try K-38 Taco stand in Baja California. It’s about 45 min south of the border (San Diego/Tijuana)

      The best! Say hi to Roberto and the familia if you get there
