Combine chicken, mayonnaise, scallions, lime juice, and cilantro. Season to taste with salt, pepper, garlic powder, cumin, and chile powder. Add a little chicken broth if chicken seams too dry, 1 tbsp at a time.
To Poach: Cover chicken breast in broth in a small pot, add water if it does not cover the chicken. Add salt and pepper, a piece of celery and it’s leaves (you could add herbs like parsley, garlic, onion, or whatever you want) and bring to a boil. Reduce to a simmer and cook 5 minutes.
Remove from heat, cover tight and let it sit for 15-20 minutes or until thickest part of the breast registers 160 degrees. Chicken will be cooked through. Let it cool and cut into small cubes.
Serve and enjoy!
