In a large pot bring salted water to a boil.
Cook the spinach uncovered in the bubbling water for about 1 minute until it gets bright green. Then immediately scald in prepared ice-water (to stop the cooking process and to keep all vitamins).
Then squeeze the spinach well and finely chop.
Wash the pepper, cut in half and cut into very fine cubes.
Peel the onion and the garlic clove, finely chop and stir with the cashew cheese until smooth. Season with lemon juice, salt and pepper. Then add the spinach and the paprika cubes.
