Getting the can out
Is there a way to lessen the canned taste of any canned foods?
Most canned foods are actually cooked in the can. Unless the can is lined (and that's not always assurance that an "off" flavor won't be imparted to the foods) there's probably nothing you can do to entirely eliminate the canned food flavor. If you drain and rinse the canned foods before cooking and use a few herbs/spices when you warm them up you may find them to be easier to tolerate.
