In a small bowl, mash together the cream cheese, mayo, chives, salt, and pepper.
In a large bowl, use a pastry cutter to mash up eggs. Finely chop the bacon and add it to the eggs.
Add the shredded cheddar and cream cheese mixture to eggs and bacon. Mix together until everything is mixed really well and the eggs are covered in cream cheese.
Serve on croissants with spinach.
