Bean shortcut - Using canned beans?

Yes, you can use canned beans, but you really don't want to cook them long with the onion and thyme, as that will make them too mushy. They'll already be very soft, right from the can.

What you should do instead is to finely chop the onion, which you'll saute over medium heat in a touch of olive oil with the thyme until the onion is soft. Then, add the beans, drained; heat gently for a few minutes, just until the beans are hot. Pour on the dressing as stated in the recipe, and proceed as instructed. ;o)
