Cook onion in olive oil over medium heat until softened, about 4 minutes.
Add remaining soup ingredients and simmer, 15 minutes.
Meanwhile, combine all dumpling ingredients in a medium bowl and mix well with a fork to form a dough. The dough should be fairly soft but not watery.
While the soup is boiling, drop the dough by heaping tablespoons onto the top of the soup. While simmering, wait for dough to float to the top and remove with a slotted spoon.
Repeat with remaining dumplings.
To serve, place dumplings in the bottom of a soup bowl and ladle soup overtop.
