01 - Preheat the oven to 425°F and line two baking sheets with parchment paper.
02 - Wash and dry the zucchinis thoroughly. Slice them into thin rounds, approximately 1/8 inch thick, using a mandoline slicer or a sharp knife.
03 - In a large bowl, combine the zucchini slices with olive oil, salt, pepper, and garlic powder. Toss until the slices are evenly coated.
04 - In a separate shallow bowl, mix together the grated Parmesan cheese and breadcrumbs.
05 - Press each zucchini slice into the breadcrumb mixture, ensuring both sides are well coated. Arrange the slices in a single layer on the prepared baking sheets.
06 - Bake for 20 minutes, then flip the chips and continue baking for another 15 to 20 minutes until golden brown and crispy. Monitor closely to prevent burning.
07 - While the chips are baking, combine Greek yogurt, lemon juice, dill, chives, garlic powder, salt, and pepper in a small bowl. Mix well and refrigerate until ready to serve.
08 - Remove the zucchini chips from the oven and allow them to cool for a few minutes to crisp up further. Serve warm or at room temperature alongside the yogurt dip.
