Add tomatoes, onion, peppers, garlic, cilantro and lime juice to a food processor. Process until fairly smooth.

Heat a large pot to medium heat and add olive oil. Add the salsa and it will sear quickly.

Add cumin and bit of salt.

Bring to a quick boil and reduce heat to a simmer. Simmer for 15-20 minutes.

Season with salt if needed and stir.

Cool and refrigerate until ready to use.
