Puppy Sandwich

Cut off the edges of the 2 slices of bread. Cut each slice in half (trim further if longer than the bento box). Spread your preferred filling, then stick the halves together to make 2 rectangular sandwiches.

Using a mold (or a knife if no mold is available), press out 4 ears from the bread edges.

Cut out the eyes from the seaweed using scissors. Prepare two straws, one thin and one thick. Use the thin straw to press out small circles from the bread edge for the nose. Use the thick straw to press out shapes from the ham slices for the puppy's cheeks. Pinch the straw to press out shapes from the cheese slices for the puppy's mouth. Assemble them together as shown.

Spread mayonnaise on everything and stick them onto the sandwiches as shown in the image.

Alternatively, you can spread the filling on an uncut slice of bread, roll it up with plastic wrap, and slice it.
