In a small bowl, cover onion with cool water to mellow it (remove the harsh bite out). Let sit for at least ten minutes, stirring once or twice, while preparing the rest of your ingredients.
Drain onion. Add to a mixing bowl with diced avocados, tomatoes, jalapeños and chopped cilantro.
Whisk dressing ingredients together in a smaller bowl until well combined.
Pour dressing over avocado salsa and gently toss to evenly combine.
Serve with tortilla chips.
Notes
For a kick of heat:Add red pepper flakes, red chili powder, or a pinch of cayenne.Onions:I prefer red onions for their flavor and color in salads, but white onions work well in a pinch too!
