Add a drizzle of avocado oil to the chicken breasts and generously season on both sides with salt and pepper.
Heat an oven-safe skillet over medium-high heat.
Add a drizzle of avocado oil.
Once the oil is shimmering, add the chicken and cook, undisturbed, for 4 minutes on each side.
Transfer to the oven and roast for another 9 minutes.
Remove the chicken from the oven and let cool before cutting/shredding into bite-sized pieces.
Once the chicken has cooled and you are ready to assemble the chicken salad, whisk together the lemony yogurt dressing ingredients (dairy-free yogurt, honey, lemon zest, lemon juice, and salt) and set aside.
Add the celery, grapes, and apples to a large bowl and toss with the lemony yogurt dressing.
Add the cooked and cooled chicken and walnuts to the bowl and toss to combine.
Taste and season with salt and pepper. Enjoy!
Notes
If you have pre-cooked or rotisserie chicken, you can skip to step 7. Simply shred the chicken, add the rest of the ingredients, and toss with the dressing!
