Great question! Our local high end grocery market has a monthly cuisine magazine and they tackled this question with suggesting serving a nicer than usual stuffed 4-cheese stuffed ravioli, topped with tomato basil sauce, and a dash of freshly grated Parmesean Reggiano. To health it up more, you could add chopped asparagus or finely chopped broccoli to the sauce.
For dessert, baked pears served warm with topped with crushed graham crackers, a drizzle of hot caramel spiced with cinnamon and a tiny dollop of real whipped cream peppered with cinnamon.
The thinking with this suggested menu is most kids (short of a gluten issue) love pasta. The tiny bite sized ravioli is easy for the toddler to eat, and if they still use their fingers is great finger food. The sauce can be served or top, on the side, or avoided altogether for the picky crew. You could just top the ravioli with either butter or olive oil and a few shakes of the parmesean and you're good.
For dessert, if the kids don't like fruit, ice cream always works well too. :)
