Start by washing the tomatoes and peppers. If using fresh tomatoes, blister them on an open flame to enhance their flavor. Chop the tomatoes into small pieces.

In a large skillet over medium heat, add a splash of oil. Toss in the chopped onion and sauté until translucent.

Add the minced garlic and cook for another minute, being careful not to burn it.

Stir in the chopped tomatoes and your choice of peppers, including seeds for extra heat if desired. Cook down the tomatoes for about 5-7 minutes.

Sprinkle in salt to taste and let everything simmer on low heat for about 15 minutes, stirring occasionally.

Finely chop the cilantro. When satisfied with the flavor and texture, turn off the heat, then add the lime juice and cilantro. Stir to combine.
