Flip the board so the bottom side faces upward and draw a semicircle at the unfinished end with a compass and pencil. This represents the cutline for a large notch/scallop that will facilitate scrapping the food from the board into a bowl.

Pass the board through the band saw and cut along the scallop tracing.

Add a drum sander to your drill press and smooth away any saw marks along the curved vertical edge of the scallop.

Install a rabbeting bit with ball bearing guides on your router. This bit will cut a recess into the bottom edge of the scallop while leaving a collar of wood on the top surface.

Turn the board bottom side up and route along the edge of the scallop to form the rabbet/recess. The recess will enable a bowl of a particular dimension to slide into the board without gaps and catch the food.
