I prefer to make salsa in my food processor or Vitamix. I like the consistency of smooth salsa, without any large chunks. If you prefer a chunky salsa, can can opt to hand chop all ingredients, rather than blend them.
Add the whole tomatoes, onion, garlic cloves, sugar, salt and ground cumin to your high speed blender or food processor and blend until smooth, approximately 10-15 seconds.
Add the diced tomatoes with green chilis, jalapeño, cilantro and fresh lime juice and pulse until you reach your desired consistency.
