Step-by-step:
step one: prep the sheet pan

step three: par-cook the veggies
Spread into an even layer and par-cook until softened, about 10 minutes.
step four: season the shrimp
Meanwhile, pat the shrimp very dry and place in a bowl. Add the remaining 2 tablespoons avocado oil 1 ยฝ teaspoons Kosher salt, ยฝ teaspoon pepper, the chili powder, garlic powder, smoked paprika, cumin, fresh oregano, and lime zest and toss until well combined and the shrimp is evenly coated. Set aside until the veggies have par-cooked.

To serve, spread the mashed avocado on the bottom of a tortilla and top with the shrimp fajitas. Finish with a sprinkle of cilantro, a drizzle of salsa, and a lime wedge for squeezing.
Recipe FAQs:
Sure! This shrimp would taste amazing over a bowl or rice, as a tostada, or even on top of a salad. Feel free to get creative!
Both! Plus, this recipe can be fully paleo depending on the tortillas you choose to use.
I wouldn’t say these fajita tacos are spicy! They have plenty of flavor, but the spice level is pretty mild. If you want to kick it up a notch, you can choose to serve with a spicier salsa! You can also avoid using the serrano pepper if you want to skip the heat.

This is my favorite defined dish meal Iโve ever made! Full of flavor and took 20 minutes from start to finish. We did tacos but would be good on a salad! Adding this in my weekly rotation!
Thank you so much for the kind review, Lesley!
These turned out perfectly – from the veggies to the shrimp *inserts drool emoji*
I canโt eat avocado, but, since I can tolerate dairy, I was able to pair it with sour cream and it was truly a delicious recipe!
Easy and delicious! Will definitely be making this again and again
Very quick and easy dinner! Full of flavor really enjoyed it!
So glad to hear that, Rebeckah
Thanks for another quick, flavorful recipe, Alex! These were delicious and came together so quickly! I chopped the peppers and onions ahead of time and then threw it all together in 20 minutes or so. Easy clean up too!
Love this recipe! So easy and so tasty!
I have made a lot of Defined Dish dinners and this is up there with being one of my favorites! So so simple but the flavors are incredible! I topped with a bit of sour cream and used corn tortillas! Can’t wait to make again ๐
