This was a movie I rented on VHS, back in the late 1980s or early 1990s. It was a quasi-medieval swords-and-sorcery fantasy, clearly made with a very low budget. It's tone was mostly serious, but sprinkled with humor. I can't really remember any of the actual story, but there is one very brief scene that sticks in my memory. A sorcerer and his apprentice (I think that's what they were) were hungry, so the sorcerer told the apprentice to try and conjure a sausage from thin air, both as an exercise and as a way to get something to eat. The apprentice tried, but he got it wrong and created a banana instead. Being from medieval Europe, neither of them had ever seen a banana. They both stared at it, and the apprentice said "What is it?" Then the sorcerer said something like "Don't know. It's passing strange. Better throw it away."
Can anyone identify this movie?
