This simple handheld tool speeds up prep work by a lot. I use mine for evenly and thinly slicing onions so that they're more palatable, and all different fruits and vegetables to get great texture in dishes. I particularly love using my mandoline to slice vegetables for pizza toppings. You can also slice up salami and cheese for great presentation. It's not as bulky as some of the other mandolines on the market, and it's a cinch to clean.
