Slice the chicken breast into thin, even strips and place them in a small bowl.
Season the chicken with sea salt, black pepper, garlic powder, and smoked paprika, tossing to coat thoroughly.
Heat the avocado oil in a large skillet over medium-high heat until shimmering.
Add the chicken strips to the skillet in a single layer and sear until golden brown and cooked through, approximately 3-4 minutes per side.
While the chicken cooks, thinly slice the cucumber and prepare the shredded carrots and spinach.
Briefly warm the whole wheat tortilla in a separate dry pan or over an open flame for 15-30 seconds until pliable.
Spread the hummus in an even layer across the center of the tortilla.
Top the hummus with the baby spinach, sliced cucumber, shredded carrots, and the warm crispy chicken.
Fold the sides of the tortilla inward and roll tightly to secure the filling before slicing in half.
