01 - Preheat oven to 425°F (220°C) and line two baking sheets with parchment paper.
02 - Wash and dry zucchinis, then slice into thin rounds approximately 1/8 inch thick using a mandoline or sharp knife.
03 - In a large bowl, toss zucchini rounds with olive oil, sea salt, black pepper, and garlic powder until evenly coated.
04 - Combine grated Parmesan cheese and breadcrumbs in a separate bowl.
05 - Dip each zucchini slice into the breadcrumb mixture, pressing lightly to ensure both sides are coated. Arrange slices in a single layer on prepared baking sheets.
06 - Bake for 20 minutes, then carefully flip slices and continue baking for another 15 to 20 minutes until golden brown and crisp, monitoring to prevent burning.
07 - While chips bake, combine Greek yogurt, lemon juice, dill, chives, garlic powder, sea salt, and black pepper in a small bowl. Mix well and refrigerate until ready to serve.
08 - Remove chips from oven and allow to cool slightly. Serve warm or at room temperature alongside the herby yogurt dip.
