Roast the kernels in a pan while turning. Puree the tofu and ajvar in a narrow tall cup with a hand blender. Season to taste with salt and pepper. Clean and wash the radicchio, spin dry and cut into thin strips.
Wash the cucumber, halve lengthwise, remove seeds, grate coarsely or dice finely. Wash, halve, seed and dice the tomatoes.
Heat the tortilla in a large hot pan without fat for about 2 minutes while turning. Remove from the pan and immediately spread with the tofu cream. Sprinkle with radicchio, cucumber, tomatoes and seeds, leaving an approx. 3 cm wide rim all around.
Fold the left and right edges approx. 3 cm over the filling towards the centre. Fold over the lower edge and roll up the wrap. Wrap firmly in sandwich paper. Keep cold overnight.
