Franzy's Soup-Kitchen (2021)

Original title: La soupe de Franzy

Alone on her asteroid, Franzy leads a happy life until she runs out of the delicious magic soup her parents bequeathed to her. She thus decides to make the soup herself but can't obtain the exact same flavour as she seems to keep leaving out an ingredient. To succeed in making the soup, she goes to the planet next door, where the inhabitants are rather sad and starving.
