Roast the almonds in a pan without fat, take them out and let them cool down. Wash the chilli pepper, cut lengthwise and remove the seeds. Peel garlic and cut it roughly into pieces.
Carve tomatoes crosswise, put them in boiling water for about 1 minute and rinse them under cold water. Skin tomatoes, remove seeds and cut into cubes. Wash parsley, dab dry and pluck off the leaves.
Place almonds, garlic, chilli, tomatoes, parsley and vinegar in a tall bowl and chop finely with the chopping stick. Then add the olive oil little by little until a soft, homogeneous mass is obtained.
Season salsa with salt and pepper.
