The basic idea is that children eat much better when their food is served in an unusual manner, which I've certainly found to be true. I'm remembering banana flowers, sandwiches cut and decorated to look like faces, and bread snakes. (I'd cut the crusts off the peanut butter sandwiches, and say, "Oooh. Bread snakes! Scary." Worked every time. Sometimes the kids even ate the "snakes" before the sandwich itself!)
So Muffin Tin Monday=Lunch served in a muffin tin. Too cute!
