Male coworker eating my leftovers in front of other coworkers. What does it mean?

Yes... this happened and everyone's eyes were on me. I wonder what his intentions are.

We just had a lunch... and he finished his plate... I had food left in mine, cause I wasn't hungry, he just randomly started eating off my plate.

We are friends, there is an attraction, but I don't know if it means something
