To make these ahead of time, mix up the egg salad mixture and then store it in an airtight container in the fridge. You can also toast the slices of baguette and then store them in a Ziploc bag or an airtight container.
This appetizer is best enjoyed the same day they’re made. However, if you do have leftovers, you can transfer them to an airtight container and store them in the fridge to be eaten within 2 days.
