let's see what you've got; show me what you've got
A set phrase used when challenging someone to demonstrate their skill, often in a lighthearted or competitive context. Literally 'let me see your skill'.
Let's see what you've got in terms of cooking skills.
I'm looking forward to seeing the new employee's presentation skills.
From お手並み (skill, ability) + 拝見 (humble 'see'). The phrase literally means 'I humbly view your skill' and is used idiomatically as a challenge.
