In even more news, I've retrieved the Sloppy Joe recipe.
When I'm stocked back up on ground beef, I'm going to make, say, two pounds each of the Manwich mix and the recipe, and the three of us here will do a proper A/B comparison. I'll post the results, and then post the recipe. I haven't tasted this one in at least five years, so I don't want to just foist it on the world without re-familiarizing myself with it.
