Cook pasta according to packet instructions. Drain. Refresh under cold water and drain again.
Meanwhile, place yoghurt, sour cream and lime juice in a small bowl. Season with freshly ground black pepper, then whisk to combine. Divide lime dressing evenly among four 3-cup capacity jars with screw-top lids.
Layer jars with salad ingredients, starting with avocado and pasta, then tomato, corn, capsicum, onion, spinach and coriander. Top with jalapeños, if using, and corn chips. Secure with lids. Tip jar contents into bowls when ready to serve.
