YES! These little bite sized snacks of glory are the perfect meal prep idea. You can pretty much do everything in advance - cook the bacon, cook the eggs, cut all the ingredients, mix the mayo. However, I don't recommend actually assembling these babies until you're ready to serve or eat them. The juiciness of the tomato and sauces will make the lettuce wilt and turn soggy as it sit in the fridge. Simply store the ingredients in airtight containers and keep them in the fridge until ready to use.
