Cut the tomatoes in chunks and drain. Mix the garlic and salt in a food processor, or finely chop the garlic by hand and add it to a blender along with the salt. If using a food processor, add the almonds and grind finely. Blend in the peppers using several on/off turns. Add the tomatoes and black pepper and mix until smooth. With the machine running, add the oil in a thin stream. Blend in the vinegar. Transfer to a bowl, cover and refrigerate for several hours. Serve at room temperature.
