In that situation, it’s a good idea to stay away from manual onion choppers. Instead, explore your options in electric models. Operation is often as simple as pressing a button, and they’re usually easy to assemble. With that said, it’s important to consider the weight of the item. If you get a heavy-duty stainless steel model, you could have difficulty pulling it out of a cupboard. A happy medium would be a lightweight, small-capacity electric chopper with a plastic base.
