01 - Preheat oven to 400°F. Line two baking sheets with parchment paper for potato chip preparation.
02 - Slice russet potatoes into 1/8-inch thick rounds using a mandoline slicer or sharp knife. Toss slices with 2 tablespoons olive oil and 1/2 teaspoon sea salt until evenly coated.
03 - Arrange potato slices in a single layer on prepared baking sheets. Bake for 15-20 minutes, flipping halfway through, until golden brown and crisp. Remove from oven and let cool completely.
04 - While chips bake, cut chicken breasts into bite-sized strips or cubes suitable for chip topping.
05 - Prepare three shallow bowls: first with 1/2 cup flour, second with beaten egg, third with panko, grated parmesan, garlic powder, salt, and black pepper combined.
06 - Dredge each chicken piece in flour, shaking off excess. Dip into egg mixture, then press into panko-parmesan mixture to coat thoroughly.
07 - Heat 2 tablespoons olive oil in large skillet over medium-high heat. Cook breaded chicken pieces 3-4 minutes per side until golden brown and cooked through. Transfer to paper towels to drain excess oil.
08 - In mixing bowl, combine shredded romaine lettuce with Caesar dressing. Toss until leaves are evenly coated.
09 - Top each cooled potato chip with dressed romaine, crispy chicken piece, shaved parmesan, and freshly ground black pepper. Serve immediately with lemon wedges on the side.
