My family has also done this for years....cream can feasts were always looked forward to in the summer. We have also done this with pheasants - put the entire cleaned pheasants in the cream can too! The pheasants always turned out very moist and tasty!
My family has done this for years! We call it a hobo dinner. One thing that we have found to make this easier is to keep the mesh bags that bulk onions come in and separate all the vegetables by bag. Much easier to get them out by grabbing a bag with a pair of tongs and without everything getting mushed. We also like to put in a big ham bone and turnips.
