Prepare the chicken:Season the chicken breasts with garlic powder, smoked paprika, cumin, salt, and pepper.Heat olive oil in a skillet over medium heat. Add the chicken and cook for 4–5 minutes per side, or until fully cooked (internal temperature of 165°F).Let the chicken rest for 5 minutes before slicing into thin strips.
Assemble the wrap:Lay a tortilla flat on a clean surface. Spread a layer of mashed avocado or lay down avocado slices.Add a generous handful of shredded romaine lettuce, a few cherry tomato halves, red onion slices, and shredded cheese if using.Place the sliced chicken on top and drizzle with your favorite dressing or sauce.
Wrap it up:Fold in the sides of the tortilla, then roll it tightly from the bottom to the top.
Serve and enjoy:Slice the wrap in half for easier eating, and serve immediately. For meal prep, wrap in foil or parchment paper and refrigerate for up to 3 days.
