bean-jam dumpling, manjuu
饅 centers on a specific filled dumpling: a bean-jam bun, known as manjuu. It refers to the food itself rather than a broader concept.
饅 combines the food radical 飠 (食) with 曼, which likely contributes the sound 'man'. The character was created to represent a specific Chinese-style steamed bun, later adopted in Japan for manjuu.
The food radical 飠 on the left tells you this is something to eat. The right side 曼 looks like a round bun with a lid and a filling inside. Together, 饅 is a filled dumpling: manjuu.
For マン, think of a man holding a steaming manjuu: man -> マン, and the bun is a bean-jam dumpling.
