Preheat oven to 375. Place the chicken breasts on a sheet pan and drizzle with olive oil. Season well with salt and pepper and roast for 15-25 minutes, until chicken is cooked through and registers 165 degrees internally. The timing will depend on the size and thickness of your chicken. When cool enough to handle, dice into small cubes. Place in a large bowl and add the mayonnaise (start with 1/2 cup and add more as needed), diced apple, celery, raisins, and curry powder. Stir well and season to taste with salt, pepper, and additional curry powder. When ready to serve, scoop onto a bed of chopped lettuce (or serve with whole leaves for wrapping). Sprinkle with cashews (don’t mix these into the salad, as they will soften) and serve with crackers.
