Close to starving to death, Sanji realized he owed his life to the man who had not only rescued him from drowning but also kept him fed. There they both realized they shared the same dream of finding the Legendary Ocean 'All Blue'. Now though, with Zeff's leg keeping him from being a pirate he shares how he'd always wanted to have a restaurant out at sea, which causes Sanji to vow that he'd help him have that restaurant one day. Finally as Zeff was growing wearier a ship could be seen in the distance, which Sanji cried out for in tears and finally they were rescued.
About 9-10 years later we meet Sanji much later in the series on the Baratie, the floating restaurant. This is where Luffy and crew first meet him. At first Luffy tried to obtain Zeff as their chef, only to be declined, afterword when meeting Sanji and finding out he's also a cook he tries to persuade him to join. Sanji also declines the offer, saying he was needed at the Baratie. An chance meeting with a starving pirate named Gin, changes everything when later it's found out he was the commander of known pirate Don Krieg, whom the commander later brings to the restaurant in order to obtain food for all their starving crew-mates. Sanji is of course blamed and yelled at by the other chefs for bringing pirates such as Don Krieg to their establishment. Sanji though, refused to let anyone starve, after his hardships he'd never let another go through what him and Zeff had.
Though food was given to Don Krieg, it was quick to see he was just as vile as first perceived as he proceeded to take over the restaurant. Through the help of Luffy they were able to defeat Don Krieg. Afterward Zeff and the other chefs tell Sanji how he should leave the Baratie. They do so in a somewhat cruel manner that causes Sanji to run outside, slumping down for a smoke only to cry. It's as he's out there that he overhears that they were merely doing it to push Sanji into doing what he should be doing for himself and so that he could finally obtain his dream of finding 'All Blue' than there on the Baratie wasting away. Hearing this, Sanji comes back in cool and composed and tells Luffy he'll go with him. This marked the day that Sanji became one of the Straw Hat Pirates and started his journey towards the Grand Line and All Blue.
