Pat the chicken breast dry with a paper towel and season both sides with sea salt, black pepper, and half of the fresh parsley and dill.
Heat the olive oil in a medium skillet over medium-high heat. Once hot, add the chicken breast and sear for 6-7 minutes per side, or until the internal temperature reaches 165°F and the exterior is golden brown.
While the chicken is cooking, prepare the sticky rice according to package instructions if not already cooked. Slice the cucumber into thin rounds and dice the avocado.
In a small ramekin, whisk together the lemon juice with the remaining fresh parsley and dill to create a bright herb dressing.
Remove the chicken from the pan and let it rest for 3 minutes before slicing into thin strips.
Assemble the bowl by placing the warm sticky rice at the base, then arrange the sliced chicken, cucumber, and avocado on top.
Drizzle the lemon-herb dressing over the entire bowl and enjoy immediately.
