Roughly chop the onion, roughly chop the garlic and cut the tomatoes into big chunks
Heat a fry pan with a medium heat and add in the olive oil
After a couple minutes add in the onion and garlic, mix with the olive oil, after 4 to 5 minutes and the onion is translucent, add in the paprika, give it a quick mix, then add in the chopped tomatoes, sea salt, black pepper and sugar, mix together, after 5 minutes and the tomatoes are lightly sauteed, turn off the heat and let the mixture cool
Meanwhile, drain the olive oil from the cans of sardines and then gently remove the sardines from the can
Once the tomato mixture has slightly cooled, add into a food processor and pulse for 30 to 60 seconds or until you end up with a smooth texture
Transfer the tomato sauce into a serving dish, add the sardines over the tomato sauce, making sure to give them a gentle flip so they´re coated in the tomato sauce, sprinkle with finely chopped fresh parsley, enjoy!
