Step 1Cook the Swiss chard stalks in a pot of boiling water to cover or steam them until soft, about 20 minutes. Drain very well and chop.
Step 2Using a mortar and pestle, mash the salt and garlic together until they form a mushy paste.
Step 3Place the chard in a food processor and puree until smooth. Add the tahineh, salt and garlic paste and process until incorporated. Pour the lemon juice into the feed tube as the processor is running until absorbed. Remove the mixture from the food processor and correct the seasoning if necessary.
Step 4Transfer the dip to a serving bowl or platter, spreading it out with the back of a spoon. Make furrows in the puree in a fan shape with the flat of a knife. Drizzle with a little olive oil and garnish with the fried pine nuts and mint. Serve the dip with pieces of Arabic bread.
