Season the chicken breast evenly with the ground cumin, sea salt, and black pepper.
Heat a non-stick skillet over medium-high heat and cook the chicken for 6-7 minutes per side until golden brown and cooked through.
Remove the chicken from the pan to rest, then add the sweet corn to the same skillet, charring it for 2-3 minutes until lightly toasted.
Slice the rested chicken into thin strips and dice the avocado into bite-sized pieces.
In a small jar or bowl, whisk together the lime juice and extra virgin olive oil with a pinch of salt to create the dressing.
In a large serving bowl, combine the mixed greens, cherry tomatoes, diced red onion, and charred corn.
Add the sliced chicken to the bowl and drizzle with the lime dressing.
Top with the diced avocado and fresh cilantro, then toss gently to combine and serve immediately.
