What those who steal eggs do when hungry? (5)
I believe the answer is:
poach
If this is the answer, I'm afraid I cannot explain it.
Can you help me to learn more?
(Other definitions for poach that I've seen before include "Cook in a simmering liquid" , "Appropriate" , "Take game illegally from land or water" , "Cook (an egg) in water" , "Steal (game etc)" .)
