In 1987 Kraft produced a 48-card set called "Home Run Heroes," which could be found on the back of Macaroni and Cheese boxes. The first two pictures below are of a complete box, still full of mac and cheese. I wouldn't be surprised it you could still eat it today!
The panels on the back of the boxes actually contained several different player combinations, four of which are shown below. Rickey (card number 31 in the set) is paired with Fernando Valenzuela (as in the full box), but also with Vince Coleman, Jeff Reardon, and Pete Rose.
