Morphology

duck + soup

The meaning 'very easy' is not derivable from the literal words 'duck' and 'soup'—there is no compositional relation that links a bird and a food to ease of task. This is an idiomatic/slang expression with a language-specific meaning, so a B1 learner who knows the constituents would not reliably infer the MWE's sense.

Etymology

Duck soup may come from a simple food idea: cooks could turn an old or cheap duck into a quick soup with very little work. One popular story says this picture of a cheap, easy dish led people to use duck soup to mean 'very easy to do'.
