Instructions

Get Started:
Preheat your oven to 425°F (220°C) and line a large sheet pan with parchment paper for easy cleanup. The smell of the oven warming is already promising.
Mix the Marinade:
In a large bowl, whisk together the olive oil and spices until they form a fragrant blend. The combination of cumin and smoked paprika will transport you straight to a Mexican fiesta.
Toss it All Together:
Add the chicken strips, bell peppers, and onion to the bowl and toss until everything is coated with that delicious marinade. Feel free to get your hands in there—it's part of the fun!
Spread and Bake:
Spread the chicken and vegetable mixture in a single layer on the sheet pan. Bake for 22-25 minutes until the chicken is fully cooked and the edges of the veggies are perfectly charred.
Finish Up:
Once out of the oven, a squeeze of fresh lime juice over the fajitas brightens the flavors. Toss in cilantro to take it up a notch.
