How to Make It
Rinse off the chicken breasts. Fill a medium stockpot with water and add the herbs, bay leaf, garlic, salt and peppercorns. Bring the water to a boil and add the chicken breasts.
Return the water to a boil and then lower heat to medium. Simmer for 5 minutes. Remove the pot from the heat, cover with a lid and keep the chicken in the hot water for another 15 to 20 minutes or until cooked through.
Remove the chicken from the water and slice into large dice. Set aside.
Heat a skillet over medium-high heat. Add the oil and then add the garlic. Cook for 1 minute or until softened. Stir in the squash and cook for 2 to 3 minutes or until tender. Stir in the Worcestershire sauce, apple cider vinegar and season with salt and pepper.
Toss the chicken in with the squash. Add the avocado and serve warm or at room temperature.
