Slice eggs in half lengthwise.

Scoop out the yolks and place in a medium bowl.

Add avocado to bowl, and using a fork, mash with yolks until fairly smooth.

Add mayonnaise, lime juice, garlic powder, cayenne and salt. Stir well to blend.

Place the filling in the whites of the eggs using a small spoon, or pipe in with a pastry bag. Garnish as desired.

Serve immediately or refrigerate in a lightly covered container.
