Maybe the food truck owner gets trapped in the dungeon by accident. He could use his cooking skills to survive, like making food from strange dungeon ingredients and trading with dungeon creatures for his freedom.
Maybe a magical creature like a talking rat. The rat could be both a friend and a source of information for the food truck owner. It could tell him about hidden passages or warn him of impending danger. Another character could be a rival food truck owner who also ended up in the dungeon. They could compete to see who can make the best use of the dungeon resources for their cooking.
Dungeon punk fiction is a genre that combines elements of fantasy, adventure, and technology in a dungeon setting. It often features unique and unconventional magic systems, mechanical devices, and a gritty atmosphere.

I recommend "Extraordinary Female Cultivator" to you. The male protagonist in the book is super strong in the female protagonist's body. The female lead was a surgeon. After she transmigrated to the cultivation world, she found that her body could not cultivate and could only rely on her mutated divine sense. The male lead, on the other hand, showed his powerful strength in a situation where there were not many scenes. Together with the female lead, they broke through a different path of cultivation. I hope you like my recommendation. Muah ~
Well, in this novel, farming in the dungeon might be special because it could involve unique crops or resources that can't be found on the surface. Maybe the dungeon environment provides some sort of magical or enhanced growth conditions for the plants.
In the ❮ Immortal Cultivation with the Sun Well ❯ and ❮ Borrowing a Dantian from the Heavens ❯, magic, battle energy, and true energy had to be stored in the body of the cultivator for cultivation.
