For serving: pita breadwhole grain bread, bibb lettuce, or crackers
Toast the nuts: Preheat the oven to 350°F. Spread the nuts in a single layer on an ungreased baking sheet. Bake for 8 to 10 minutes, until crisp, fragrant, and toasted. Set a timer and do not walk away from the oven during the last few minutes, as nuts can burn the moment you stop watching. Immediately transfer to a cutting board. Let cool a few minutes and roughly chop.
In a large bowl, place the diced chicken, celery, grapes, green onions, and toasted nuts.
In a separate bowl, whisk together the Greek yogurt, lemon juice, maple syrup, curry powder, garlic powder, salt, and black pepper until smooth.
Pour the dressing over the top of the chicken mixture. With a big spoon, stir gently to evenly coat and combine.
Enjoy cold or at room temperature inside a pita, on toasted bread, wrapped with lettuce, dipped with crackers, or over a bed of greens
