I had a children's book when I was a kid. I don't remember the name unfortunately; there was a woman who owned a restaurant, but only served canned spaghetti and the food was awful. One day the can she chooses from her pantry -- filled exclusively with canned spaghetti -- contains a genie. This book was published likely in the 70's, based on the art style.
If anyone remembers this book I would love to know it!
