Preheat oven to 400°.
Cut each pita half into 8 wedges to form 64 wedges. Arrange wedges in a single layer on a baking sheet. Lightly coat wedges with cooking spray; sprinkle evenly with garlic powder. Bake at 400° for 7 minutes or until lightly browned and crisp.
Heat oil in a large saucepan over medium-high heat. Add onion to pan; sauté 4 minutes or until lightly browned. Stir in raisins, cilantro, peas, mango chutney, curry powder, cinnamon, cumin, pepper, chickpeas, and salsa. Reduce heat, and simmer 10 minutes or until slightly thick. Serve with pita chips.
