Checkerboard Sandwiches

Ingredients

Directions

Remove the crusts from the white and brown bread, creating uniform blocks.
Cut the blocks lengthwise into 1-inch thick slices, then into 1-inch wide strips.
Arrange the strips in a checkerboard pattern, three blocks wide and three blocks deep.
Mix butter with grated cheese and a little red pepper, then spread it on the bread.
Chill thoroughly before slicing.
