These grilled chicken tacos get a major upgrade thanks to a bright key lime slaw.

Who’s ready to eat ALL THE TACOS next Tuesday? And who’s bringing a margarita?

We have tacos at least once a week and I’m always hunting for a new twist — something beyond the classic ground beef tacos I grew up with. I still love the old favorites, but I can’t resist trying something fresh and unexpected.
Grilled chicken might sound simple, but the marinade here is built to deliver flavor, especially after it sits for a while. And the slaw? That’s where these tacos really shine.
Oh my gosh. THE SLAW!

I’m obsessed with this slaw. We’re a very pro-slaw family — Eddie loves slaw on tacos and alongside pulled pork, and while I never cared much for classic mayo-heavy coleslaw, any vinegary, briny slaw is my dream. I would happily eat this slaw on its own.
The crunch and bright flavor add texture and lift to every bite. Making the slaw with key limes is what makes it extra special: lime zest, fresh lime juice, a touch of sugar and salt. As it sits the slaw develops a perfect tangy, slightly sweet lime profile that pairs beautifully with smoky grilled chicken.

The tacos themselves remain simple so the flavors complement rather than compete. Top them however you like — I use sliced avocado (rather than guacamole), a light sour cream drizzle or crema, thinly sliced radish for extra crunch and bite, and crumbled cotija cheese. A sprinkle of tajín or smoked paprika finishes things perfectly.
