Season the chicken breasts with kosher salt and black pepper. This simple step sets the foundation for flavorful meat that shines through in every bite.

Sauté the onion in olive oil over medium heat until it turns golden brown. This should take about 5-7 minutes and will fill your kitchen with a delicious aroma!

Cook the chicken in the same skillet until it's tender, about 6-8 minutes, then cube it into bite-sized pieces for easy wrapping.

Combine the cubed chicken with the prepared white rice, fresh cilantro, lime juice, and baby spinach in a large bowl. Mix until well incorporated for a colorful and flavorful filling.

Spread a portion of the chicken mixture onto each tortilla, ensuring an even distribution for a perfectly satisfying wrap.

Drizzle the creamy sesame sauce over the filling, followed by a generous sprinkle of shredded Monterey Jack cheese, which will melt beautifully inside the wrap.

Roll up each tortilla securely, tucking in the sides to keep all the delicious contents inside. Cut in half if preferred, and serve immediately.
