An onion chopper includes a food reservoir supporting a blade tray and having a lid attached for pivotal movement toward and away from the lid and blade tray. The lid includes at least one grid of projections configured to push through a corresponding grid of blades in the blade tray to chop the onion. A cleaning grid is provided for attachment to the grid of blades. The grid of blades forms a peripheral skirt surrounding a lower container for collecting bits of chopped onion or other foods.
