I believe the answer is:

stone me

I'm a little stuck... Click here to teach me more about this clue!

'how amazing to' is the definition.
I can't tell whether this defines the answer.

'welcomed by host one meets' is the wordplay.
'welcomed by' says the answer is hidden in the clue.
'STONE ME!' can be found hidden inside 'host one meets'.

'be' is the link.

Can you help me to learn more?

(Other definitions for stone me that I've seen before include "I'm surprised" , "Astonished exclamation (colloq.)" , "Well I never!" , "Crikey!" , "Wow" .)

I've seen this clue in The Times.
