These 2 mangas are by right, fundamentally different, but carry similar traits.
Similar: Both the main characters have this initial introduction of one that has overcomed many obstacles and opponents, then they start on a journey due to some reasons, and start facing more powerful opponents at a high risk.
They are very shounen-ish and reminds me of One Piece. The main guy character's design is kinda similar too.
Different: Shokugeki is a cooking manga with a side focus on ecchi while Gamaran is a samurai manga focusing on sword techniques, combat instincts and the like, and has consideable gore.
