The Greatest One Star Restaurant in the Whole Quadrant

The Greatest One Star Restaurant in the Whole Quadrant by Rachel K. Jones. The story of five cyborgs who hijack a human ship and cook it up for humans to eat. It takes place during their escape from Orion's Alpha, where they had been working as guests at a luxury resort. They are forced to make food out of anything that can be microwaved or cooked with enough chemicals to kill an entire person.
