Rinse the split peas with cold water and place in a large pot with the grated onion, olive oil and water. Stir once and then let them cook over medium heat. Add salt 15 minutes after they come to the boil. Stir often to avoid sticking to the bottom of the pot. After the split peas start dissolving into the water, continue cooking until they thicken; if the split peas have not completely dissolved, wait until they have cooled and purée them in the blender. After they have cooled empty onto a serving dish, preferably oblong.
Pour a few tablespoons of olive oil over the split peas then add the onion, capers and sun-dried tomatoes and the 2-3 tablespoons of lemon juice.
