Similar to a green salsa, this green taco sauce is packed with roasted peppers and citrus. It's great drizzled on almost any taco from fish tacos to beef!
Add peppers, onion, and garlic to a sheet pan and drizzle with olive oil and season with kosher salt. Roast for 20-25 minutes at 500˚F. Let cool briefly.
Scrape skin off the peppers and slice them in half to remove seeds and stem. Add all ingredients to a blender along with water and blend until very smooth.
Taste the sauce and adjust to your liking. It should be salty, spicy, and bright with citrus.
Transfer sauce to a squeeze jar or bowl for serving. Store leftovers in the fridge.
