Cook the Chicken: Season chicken breast with salt, pepper, and spices. Cook on a grill or skillet over medium heat until fully cooked (about 6-7 minutes per side). Let it rest, then dice.
Prepare the Kale: Wash and chop kale, removing tough stems. Massage kale with a pinch of salt for 2 minutes to soften leaves.
Combine Ingredients: In a large salad bowl, combine chopped kale, diced chicken, halved cherry tomatoes, and sliced avocado.
Dress the Salad: In a small bowl, combine olive oil, lemon juice, salt, and pepper, then whisk together. Pour dressing over the salad and toss to coat evenly.
Serve: Enjoy your chicken and kale salad! Optionally, garnish with more avocado slices or seeds.
