Preheat a grill or grill pan to medium high heat. Clean and oil the grates.
Spilt an avocado in half and remove the pit. Place cut side down on the preheated grill and cook for 3-5 minutes until grill marks form. Flip and cook 2 more minutes.
Remove from heat, and let cool slightly. Once cool enough to handle, peel and chop into 1/2 inch cubes. Set aside.
Shred the chicken into large chunks, using mainly the breast meat. Set aside.
To make the dressing, combine everything in a small bowl or jar and mix. Taste for seasoning.
To make one salad place some of the spring mix in a bowl or plate. Top with a sprinkling of feta, some of the basil pieces, shredded chicken and chopped, grilled avocado. Drizzle with dressing.
Recipe makes up to 4 salads.
