We had this at one point too. Turns out they weren't hungry, so we changed such that the food is there but they choose whether they want to eat. Instead of eating they could bring a piece of paper and do drawing or tell us about their day for a bit while we sit together.

It worked well as it was a lot calmer and the transition to bed wasn't as big an hour or so later.

Not saying it will work for you, but it helped us.
