Your coworker was asking you to move the meat to your side of the table.
“To pull” is used as a generic verb for moving objects, but also specifically refers to the act of moving something closer to you. The same is true of “to push” which is used as a generic verb for moving objects and also specifically meaning to move an object away.
“Over” here is specifying the direction of pulling. The coworker wants you to “pull it [the meat] over [to your side].”
This is all tracking with the common and literally meanings of the terms. The phrase “to pull over” meaning “to stop while acting as a police officer or similar” comes from shortening “to pull over to the side of the road.” When a cop tries to get you to stop driving, you’re supposed to pull over to the side of the road (literal meaning here). The term “pull over” has been used in this context so much, it has taken on a metaphorical meaning referring to any stopping of a suspect by police or similar.
