assembly 24 comprises a first arm 241 and a second arm 242 the first arm 241 comprises a proximal end portion 2411 and a distal end portion 2412 the proximal end portion 2411 is pivotally coupled to the pivot end 221 of the base plate 22 by a first pivot such as a pin or a rivet so that the first arm 241 is pivotal relative to the base plate 22 between a closed position in proximity to the base plate 22 and an open position away from the base plate 22 a plurality of downward protrusions 2413 extend from an inner surface of the distal end portion 2412 of the first arm 241 to form a blade grille the protrusions 2413 are ideally arranged to push an onion to be processed through the blade grille 262 and each of the protrusions 2413 is positioned to cooperate with a cell of the blade grille 262 when an onion or the like is placed on the cutting plate 26 and the first arm 241 is pivoted to be in the closed position the protrusions 2413 would be pressed against the onion or the like which are then pressed against the blade grille 262 the onion or the like are pressed and pushed to run through the openings defined by the blades of the blade grille to allow the cutting of the onion or the like into granules the onion granules directly fall into the container 28 the second arm 242 is pivotally coupled to the distal end.
