Boil the Vegetables: Bring a medium pot of water to a boil. Add the jalapeños and onion, cooking for about 10 minutes.

Prepare the Jalapenos: Remove the boiled jalapeños and onion, let cool, then slice off stems and remove some seeds if desired.

Blend the Ingredients: In a blender, combine boiled onion, jalapeños, oil, salt, black pepper, garlic powder, and lime juice. Blend until smooth.

Adjust the Seasoning: Taste and adjust seasonings. Add reserved boiling water if desired thickness is not achieved.

Let it Rest: Allow the salsa to rest for at least 15 minutes before serving for the flavors to meld.

Serve and Enjoy: Spoon salsa into a bowl and serve with tacos, burritos, or tortilla chips.
