In a medium bowl, stir cream cheese vigorously to loosen. Add almonds, green and black olives, and pepper, stirring to combine. Spread an even layer of cream cheese mixture onto 2 bread slices. Stack bread slices, cream cheese side up, on top of each other. Cover with a plain bread slice to create a triple-stack sandwich. Repeat with remaining cream cheese mixture and bread slices to create 4 more triple-stack sandwiches.
Using a serrated bread knife in a sawing motion, cut and discard crusts from sandwiches. Cut each sandwich diagonally into 4 equal triangles. Serve immediately, or cover with damp paper towels, place in a covered container, and refrigerate until serving time.
