Step 1

Heat the oil in a large saucepan to medium heat. Add onion and peppers and cook for 5 minutes to soften.

Step 2

Add the garlic and cook another minute, until garlic becomes fragrant.

Step 3

Add remaining ingredients and stir until everything is combined. Bring to a boil, then reduce heat and simmer for 10 minutes to let the flavors mingle. You can simmer longer if you'd like.

Step 4

Option 1: Strain into a serving container and use as desired.

Step 5

Option 2: Transfer the ingredients to a food processor and process until smooth for a thicker version. Use as desired, or strain to thin it out, plus more vinegar or water to thin as desired.

Step 6

You can serve this right away, or let it sit awhile to allow the flavors to more fully develop. Store in the refrigerator in a sealed container.
