Yes! There are two ways to do it: If making a few hours ahead: Assemble everything EXCEPT do not brush on the honey butter. Cover tightly and refrigerate a few hours until you are ready to bake it. Right before baking, drizzle on your honey butter. Keep in mind, you may need to add a few minutes to the cooking time if it's coming straight from the fridge. If making the day before: If you want to make this the night before, I suggest scrambling your eggs and storing them in the fridge in an air tight container. That's really the only time consuming part of the process. Then, when you are ready to eat, you can assemble the sliders in minutes.
