A square image of a minimalist, flat-style cross-section of a sushi cake. Each ingredient is represented as a simple, solid-colored horizontal stripe with no textures or shading: top layer with black sesame seeds, white rice layer, a thin nori strip, a red crab meat layer, a bright red stripe for fish roe, a smooth cream cheese layer, a pink stripe for salmon, green cucumber slice layer, light green for avocado, another thin nori strip, and bottom white rice layer. Each layer is evenly spaced, with clean lines and solid colors, in a graphic, flat design style.
