I have a can-opener easy to use with one hand. Once the can of fruit or vegetables is open, you need to drain the liquid. I found a small dishwasher-safe “can colander” that fits over the top of the can, the “Prepworks by Progressive Can Colander , Can Strainer, Vegetable and Fruit Can Strainer, No-Mess Tuna Can Strainer.” I can easily hold the colander on top of the can and turn it over in the sink so it drains without worrying about cutting my hand or losing the contents.
Since canned vegetables have added salt, I try to rinse some of the salt off. After draining the liquid, I run a little tap water into the can, put the colander on top, shake, then drain, repeating a few times.
