Preheat your grill or grill pan over medium-high heat.
Season the chicken breast with a pinch of salt, pepper, and your choice of dried herbs to enhance the herb flavor.
Grill the chicken breast for about 6-7 minutes per side or until fully cooked, then let it rest for a few minutes before slicing thinly.
Warm the whole wheat tortilla slightly on the grill or in a skillet to make it more pliable.
In a bowl, toss the mixed greens, sliced tomato, cucumber, and red onion with olive oil, lemon juice, and fresh herbs.
Lay the warm tortilla flat and place a generous layer of the dressed veggies in the middle.
Add the sliced grilled chicken on top of the veggies, then roll the tortilla tightly to form a wrap.
Slice in half if desired and serve immediately, enjoying the fresh combination of flavors.
