Thankfully, the Internet is full of wonderful ideas like this one. Save and wash Styrofoam egg cartons. Line them with lettuce, spinach or other greenery. When making your deviled eggs, cut them across the middle (instead of end to end) so they will sit back in the egg carton. Fill the eggs, close your container and you are ready to travel.
When we arrived on site, we cut the top and flap off the carton and put frilly tooth picks in each egg for easy serving. Now that's the way to travel with deviled eggs! Yay!!!
