My now 19 year old remembers having Bolognese for breakfast when he was 4.
He just refused to eat it for dinner. It was his absolute favourite dinner and he point blank refused! He was told he could get down from the table and asked for food several times, was offered his dinner and still said no. He went to bed hungry, came down a couple of times was offered his dinner said no and went back to bed.
When he got up in the morning, he ate every single bit of his Bolognese said it was lovely was there any more and then went on to eat some weetabix and toast!
Slightly different to your issue, but just to reassure you that no harm will be done for missing a meal!
Does your daughter have smaller cutlery that she can manage ok, do you serve her food on a smaller plate, or even let her dish up what she wants? we found that putting too much food on my son's plate really turned him off eating, so smaller portions and coming back for seconds worked better.
Every time she asks you to feed her, I would just say no, you are a big girl now you can feed yourself. We also set timers for eating otherwise it went on all night, so 45 minutes was more than long enough to eat up and still chat at the table. Anything not eaten after that time was cleared away and he wasn't allowed to top up with snacks or supper. It was dinner or nothing.
At that age he had dinner about 4.30, 5pm and I sat with him whilst he ate, as he got older I just pushed his dinner time out until it met ours and then we all ate together.
At this point, you might just need to out stubborn her!
