These tacos don't need much, but a few slices of avocado and a squeeze of fresh lime are nice finishing touches. You can also prepare the avocado as a simple, creamy-style guacamole using a few additional ingredients—see TIP B below for these instructions. These tacos are great served make-your-own-style or pre-folded.
TIP A: If you didn't grow-up on the docks, buying fish can be a bit intimidating. I've felt that intimidation...until one day I just decided to get over it. And really, it's quite simple if you have an idea for how you want to prepare and serve your fish before your go shopping, and you go to a reputable fishmonger that receives fresh fish daily (for me, this is Whole Foods Market®). Then, just follow this script:
"I want to make _____ [e.g. grilled fish tacos], what type of fish do you recommend?...Why do you recommend that one? [Listen for texture and flavor reasons, not sale and price reasons]...Ok, great, can you remove the skin and bones for me?".
Always ask them to remove the skin and bones! This will save you a lot of time and struggle. When it comes to grilled tacos, I've had this conversation a number of times, and I've tried many options. The most common fish recommended to me and my preferred option is mahi mahi—firm, yet breaks apart nicely for tacos and typically falls in the middle-of-the-road for price. I've also tried tilapia when I was looking to save a few dollars and it is good too—just a bit more flakey and "fish-forward" in taste. If you want to splurge, you cannot go wrong with halibut or Chilean sea bass. Primo!
TIP B: If you really want to impress by preparing a homemade guacamole for your tacos instead of avocado slices, I've got you covered! Simply mash 2 avocados with the juice of 1/2 a lime, a splash of o.j. (whatever you or your kids drink for breakfast as long as it is 100% juice and not from concentrate), 3/4 tsp. kosher salt, 1/4 tsp. granulated garlic (coarse garlic powder), and 1/4 tsp. fresh ground black pepper. This will become your go-to,easy guac recipe and you'll never do store-bought again. It's creamy, tangy, great with chips or topped with toasted pepitas, and perfect to dollop on these fish tacos!
