Morphology
The idiomatic meaning 'that's all; it's simple' cannot be derived from the literal constituents 'Bob's' (a personal name), 'your' and 'uncle' — knowing those words does not signal the pragmatic sense. The expression is culturally specific and historically opaque, so a B1 learner who knows the component words would not reliably infer its meaning.
Etymology
Bob's your uncle may come from an old British story about a leader named Robert 'Bob' who gave his nephew a good job very easily. The idea is that if Bob was your uncle, things would be fixed quickly and without trouble, so today the phrase means 'it's easy' or 'you're done'.
