Remove yolks from halved eggs and place in a medium bowl. Mash the yolks with a fork and then add the mayonnaise, cheddar cheese, sour cream, chives, and 1 1/2 teaspoons of taco seasoning. Mix together well.
Place mixture in a resealable plastic bag, snip off the corner, and pipe into the cooked egg whites.
Top with finely diced avocado and chives. Using a strainer add the remaining 1/2 teaspoon of taco seasoning and very lightly dust the eggs with it. Refrigerate until serving.
Recipe Notes
You can use green onions instead of chives but chives are much more delicate - perfect for little deviled eggs. 3.2.2885
