Yup, there is nothing wrong with bringing home a rotisserie chicken, even if you love to cook. Get over yourself! It’s hot! Take the help.
Pull or chop the chicken meat into bite-size pieces. Discard the skin and bones or reserve for another use.
In a large bowl, whisk the lemon juice, ginger, and garlic; season with salt and pepper. Whisk in the yogurt, chutney, oil, and spices. Fold in the chicken, grapes, half the nuts, the apple, onion, celery, herbs, and chile; season.
Arrange the lettuce leaves on plates. Fill the leaves with the chicken salad. Top with the scallions and the remaining nuts.
