Slice each peeled egg lengthwise in half. Using a small spoon, gently remove the yolks and place them in your mixing bowl. Arrange the whites on your serving platter or a clean sheet pan.
To the yolks, add:
The flesh of your ripe avocado (scoop it out cleanly with a large spoon)
1 tbsp mayonnaise (if using)
1 tsp Dijon mustard
2 tbsp fresh lime juice + lime zest
½ tsp garlic powder + ¼ tsp onion powder
1 tsp hot sauce
Salt, pepper, and cayenne
Start mashing with a fork until the avocado and yolks are roughly combined, then switch to a hand mixer or food processor and blend until the filling is completely smooth, creamy, and lump-free. Fold in the fresh cilantro and chives by hand — you want those herbs visible and textured, not blended away.
Taste. Adjust salt, lime, or heat to your liking. The filling should be bold, bright, and rich.
