A close-up, high-angle shot captures a freshly made sandwich, resting on a white marble surface with subtle gray veining. The sandwich features two slices of lightly toasted white bread, golden-brown on the crust and a paler golden in the center of the toast. Between the bread, a generous filling is visible, including a dark brown circular patty with a textured, grain-like appearance, suggesting a veggie burger or a heavily seasoned meat patty. Below the patty, there's a crisp, vibrant green lettuce leaf, and a thin slice of bright red tomato. On the other side of the patty, under the top slice of bread, a slice of purple-red onion is nestled, along with another layer of fresh green lettuce and a thin slice of green cucumber. The bread slices are slightly askew, revealing the layers of ingredients. Small, light brown crumbs are scattered on the marble surface around the sandwich, hinting at the freshness of the toasted bread. The lighting is bright and even, highlighting the textures and colors of the sandwich components.
