Toast the almonds in a small dry skillet over medium heat. Keep an eye on them because they go from brown to black pretty quickly.
In a large bowl, mix the yogurt, mayo, and curry powder. Fold in the chicken, grapes and cilantro and season with salt and pepper. At this point you can store in the fridge for up to 3 days.
When you are ready to serve. Put a scoop of the chicken salad on a bed of greens and sprinkle with the toasted almonds. Add a lemon wedge to squeeze over the greens right before eating. Serve with pita chips.
