slab
The word "slab" usually refers to something heavy and solid. When talking about construction, it is often used as a countable noun (e.g., "a concrete slab"). When referring to food, "slab" implies that the piece is quite thick and perhaps roughly cut, rather than a thin slice.

🎬Tuesday afternoon on the Martian outpost, Tom is staring at a small food ration.

I'd kill for some real cake instead of this flavorless slab of protein.

Your dietary grievances are noted, but your ration-slab placement violates Sector 4 zoning laws.

Tom uses the idiom 'I'd kill for' to express intense longing for Earth food. Xylar ignores the emotion and focuses on a bureaucratic violation regarding where the food is placed, maintaining their role as an annoying regulator.
