Super yummy and so easy. It was a bit spicy and I'm a wimp but the avocado sauce helped temper the heat. I had mine over a bed of arugula and cabbage. Everyone else had it street taco style.

I would give it 6 stars if I could. I just had blackened rockfish tacos in Victoria, British Columbia, and these were better than what I had there....and they were excellent. I will make this regularly. The avocado cilantro sauce I could eat right out of the bowl. At first I thought, 2 cups of cilantro seems like quite a bit, but the flavor just pops! I shredded up some fresh grown kale from our garden (to substitute for cabbage), and this was one of the best dishes I ever cooked from home. I would be more than happy ordering this from any restaurant in the country! Amazing job, Danielle!!!

Thank you so much Eric for your incredibly sweet comment and rating! I am so glad you enjoy this recipe:-)! It is one of our favorites!
This was delicious and really simple to make! Instacart accidentally delivered flat leaf parsley instead of cilantro, and the sauce was still really good. I added an extra squeeze of lime juice and a few shakes of cumin to compensate for the switch and it worked great. My only change for next time would be to add only half or 2/3 of the water to the blender at first & check the consistency to see if you need more. Our medium sized avocado felt stretched just a little thin with the full cup, but it was still amazing.
