Preheat a grill or grill pan over medium-high heat.
Season the 4 ounces chicken breast with chopped fresh herbs, a squeeze of lemon juice, salt, and pepper.
Grill the chicken for about 6-7 minutes per side until it reaches an internal temperature of 165°F.
While the chicken is grilling, prepare the vegetables. Chop mixed lettuce, slice the tomato, cucumber, and halve the red bell pepper (using only half as needed).
Warm the whole wheat wrap on the grill for about 30 seconds on each side.
Once the chicken is done, slice it into thin strips.
Assemble the wrap by spreading hummus over the tortilla, adding the grilled chicken strips, and layering with fresh veggies and a few slices of avocado.
Drizzle the remaining lemon juice over the fillings and sprinkle with additional chopped fresh herbs.
Roll the wrap tightly, slice in half if desired, and serve immediately.
