A simple dessert like pudding, or fruit, in a fancy glass works wonders at our house. We also have had "hotdogs" and s'mores cooked in the fireplace.
"Dagwood" (build your own) sandwiches are a hit.
Different colored food some times works. - Not Matrimonial Cake with green icing! My sisters choice for a birthday cake when she was a child. Now part of our family history.
Eating with kitchen utinsils, or without any utinsils, makes a meal fun for kids. Try eating spagettii with your fingers!
Learning to use chop sticks with the rice takes the fun up too.
Having children prepare the meal, or a dish within the meal, makes anything a Royal supper. Stephanie think how royal you would feel every night of the week if the kidos made supper.
