Well you just read about how sacred and important the family meal is I guess.
But that is not about food content, IMO. Just because we are eating abendbrot for dinner at our house does not mean we are walking around like wolves while we eat it! I put the breads, deli meats, cheeses and vegetables on the table and we sit down together and still eat together. DS gets down when he is finished, within reason. I am encouraging him to sit and have conversation with us for at least 30 seconds
before he runs off, but it also depends on tiredness, time, etc Sometimes he sits for a while other times he does not.
But just because it is bread and butter does not mean you can not have it as a family meal, right? We all sit down together, we pass the bread basket around and we have a nice talk about what we did today, and we eat together. Still a family meal!
On nights when DH and I are not eating with DS (if he has not napped he goes to bed at 5pm) he eats at his little table int he living room watching TV. I sit down at a little chair with him and we chat, I don't just leave him to it.
