I echo what Dixie just said, my nearly 3.5yr old DD is at nursery 2 days a week and their 'tea' is always lighter. they had Tomato soup with homemade bread today, with fruit for dessert. She had a cooked lunch of lasange with peach cobbler for pudding at midday. Plus they have a snack at 10pm and one at 2.30ish.
She did have an apple and a few breadsticks at home later because shes a pig at the moment!
I reckon your DD is eating very well, does your friend have food issues? I'm not sure I would ever comment on what one of my friends DC's had for tea etc as I know what difficulties some people have getting kids to eat anything at all.
