I Run a Canteen in an Infinite-Turn Survival Game

My name is Lin Zhou, and I'm a chef who couldn't make it in the real world. The moment I open my eyes, I'm thrown into an infinite game called "Abyss of Gluttony." Other people start with knives and guns, but all I have is a kitchen knife I brought from the real world. The System tells me my starting class is... [Cafeteria Chef]. In dungeons crawling with ghosts and monsters, everyone else is trying to escape while I'm tossing food in the kitchen. Sadako, big sis, care to try my freshly made Soul-Calming Spicy Hot Pot? Slit-Mouth Woman, your order of "Painless Lip Plumper" (special chili sauce) is ready. While all the other players struggle in despair, my cafeteria quietly opens for business, trading a serving of egg fried rice for a top player's life-saving item. Later, even the final boss knocks on my window, drooling as he asks, "Boss, could I... get a monthly meal plan?"
