Sheet Pan Chicken + Veggie Fajita Lettuce Wraps

Today is National Fajita Day (yes, there is a “national day” for literally everything), so you better believe we are celebrating accordingly! Did anyone else think fajitas were like, the coolest thing to order at a Mexican restaurant when they were younger because of the crazy sizzling sound they make as they announce their presence at the table? No? Just me? K.

I never would have imagined that I could make that crazy-cool dish from the comfort of my own kitchen. We’re on a constant mission to make dishes as easy and healthy as possible, which is exactly how these sheet pan fajita lettuce wraps came to fruition. Okay, so these don’t make the cool sizzling sound that restaurant-style fajitas make, but we promise you, they taste just as good!

We’re big fans of sheet pan meals because, well, obviously—less dishes to wash. Another thing we’re big fans of? Subbing Greek yogurt for sour cream! We’ve learned over the course of this little blogging venture that Greek yogurt is versatile AF. Swap it out for sour cream or mayo in almost any recipe and it tastes virtually THE SAME. Clearly still mind blown over here…

While we could have kept these fajita lettuce wraps basic, with just chicken, peppers and onions, we figured we might as well capitalize on summer while we still can. So, we invited zucchini and yellow squash to the party. Too much of a good thing when it comes to vegetables? Never. Happy celebrating!!
