In a blender, add tomatoes, onion, peppers, garlic, cilantro, and lime juice and blend until fairly smooth.

Heat olive oil in a medium pot on medium heat. Add the salsa mixture slowly as not to spatter. Add cumin and maybe 1/2 tsp sea salt or to your taste.

At medium-high heat, bring to a boil. Reduce to low and simmer 15 mins.

Remove from heat and let cool for about 15 mins. Taste and add salt if necessary.

Pour into air-tight container or squeeze bottle (just like in the taco shops!) and refrigerate until cold and has had a chance for the flavor to develop.

You can use it as soon as it's chilled but it will be at it's best after a couple days. ENJOY!!
