Release date: Maybe the 90s, the questioner saw it in the early 2000s.
“I can only remember one scene, but there was a queen being held prisoner. She was crying because it was her birthday and wanted to at least have some sort of sandwich (I think avocado) and some tea for lunch. The henchmen was going to go find it for her until the big bad guy stopped him. I think it was one of the Swan Princess movies but I could be wrong.”
