Preheat your grill or grill pan to medium-high heat.
In a small bowl, mix olive oil, smoked paprika, garlic powder, cumin, salt, and black pepper to make a marinade.
Brush the marinade evenly over both sides of the chicken breasts.
Grill the chicken breasts for 6-8 minutes per side or until fully cooked and the internal temperature reaches 165°F (74°C). Remove from the grill and let rest for 5 minutes before slicing into thin strips.
While the chicken is grilling, prepare the avocado spread. Scoop out the flesh of the avocados into a bowl, add lime juice and chopped cilantro, then mash until smooth and creamy.
Warm the tortillas on the grill or in a dry skillet for 30 seconds on each side until pliable.
To assemble the wraps, spread a generous layer of the avocado mixture onto each tortilla.
Add a handful of shredded lettuce, diced tomatoes, sliced grilled chicken, and a sprinkle of shredded cheddar cheese over the avocado spread.
Optionally, add a dollop of sour cream for extra creaminess.
Roll up the tortillas tightly into wraps, slice in half, and serve immediately.
Notes
For extra flavor, add a pinch of chili powder to the avocado spread or use a flavored tortilla.
