Slice the chicken breast into thin strips and place them in a small bowl.
Season the chicken with sea salt, black pepper, garlic powder, and smoked paprika, tossing to coat evenly.
Heat the avocado oil in a non-stick skillet over medium-high heat.
Add the chicken to the skillet and cook for 5-7 minutes, turning occasionally, until golden brown and cooked through.
While the chicken cooks, thinly slice the avocado and set aside.
Warm the tortillas in a separate dry pan for 30 seconds per side until pliable.
Lay the tortillas flat and layer each with half of the baby spinach and the cooked chicken.
Top with the avocado slices, fresh salsa, and a dollop of plain Greek yogurt.
Roll the tortillas tightly, tucking in the ends, and serve immediately.
