Add the red onion, scallions, garlic and jalapeño to the bowl of a food processor. Give it a buzz or two until chopped.
Add the tomatoes without juices, spices and cilantro on top and pour in the lime juice.
Very carefully press the pulse button a few quick times making sure you don’t over chop the salsa. (Alternately you can chop everything by hand for a chunky version)
Transfer to a bowl and taste seasonings. Add more lime and sea salt if desired. At this point you can add the reserved tomatoes juices if you are wanting a thinner consistency. Add more smoked paprika for a deeper smokier flavor.
