6 year old wont swallow her food.

I have two kids. A son who is 3 and daughter who will soon be 6. My son is a great eater. He will eat a berger and fries then as soon as we get home he wants to eat again. But on the other hand, My 6 year old has all the time in the world to eat. and just sits there with the first bite of food for hours in her mouth.
When I say hours I mean hours(7 or 8 hour). It's usually food she would normally eat(eggs,mcds,pasta,rice,....). She has been doing it since she was 2. I first noticed it with a cherry tomato, my sister gave her one to eat and that was the end of it, so we thought. When she woke up the next morning I noticed she wouldn't say anything. I grew suspicious and asked her to open her mouth,when she opened up I saw what was once a tomato(now sauce) in her mouth. I was shocked, I couldn't believe  a person could possibly do that. Well she can and has till this day.
We don't give her candy or sweets(only on birthdays), mostly healthy foods, never any junk food.
Her pediatrician tell's me just make the food ready and just let her get it when she wants("no child will ever starve them self"). I've tried doing that and went on for 3 days with her telling me she didn't want to eat.
When she finally gave in she still kept the food in her mouth for about 45 min (each bite). The Doc has told me time and time again that shell grow out of it, obviously thats not the case.
I don't know what to do.
So for you people who like to say we have no time or that we rush them. Thats not true.

Well to update on my daughter.
she's doing fine. After about 4 days of stubbornness she finally decided she wanted to eat.
She now eats everything we give her, no fussing.
I think she's been pushing her boundaries.My mother and father which no longer live with us(2 months) would always give her honey in the morning and mix sugar in her eggs and would always do what I would ask them not to.
I didn't get it either, If i said sit they would tell her get up.
when i said finish they'd say stop eating.It drove me crazy.
Now that were in separate homes she's much better but it did take her 2 months to adjust to our rules and not grandmas/grandpas.

I wouldn't wait to see if she outgrows this!  I would make sure there isn't anything causing her pain when she swallows, or if she has developed a fear of swallowing her food, which if she has, needs to be addressed by a child psychologist.  She is going to a lot of effort to not swallow, and I have to believe she has a good reason.  She is lucky to not have choked on that cherry tomato.  I think at 6, there are other things she'd rather be doing than trying to keep from swallowing her food. Take her to a Pediatric Gastroenterologist to make sure she is swallowing properly, and if so, then seek help with this fear she has developed.  You have to be terribly worried!  I do wish you both all the best, and take care!

Is he getting enough nutrition? Is she of normal weight? If she is, take your doctor's advice and let her grow out of it.
