Place beans, tahini, lemon juice, 2 garlic cloves, anchovies and red pepper flakes in a food processor and pulse.
Add 1/4 cup olive oil in a steady stream, with the motor running until incorporated. Scrape down the sides occasionally. The dip should appear smooth and creamy. If you prefer a less thick consistency, add more olive oil.
Taste for salt (the anchovies should suffice, but you may want to add some more salt).
Transfer to your serving dish.
Heat 2 tablespoons of olive oil in a small frying pan. Sauté chopped garlic till golden.
Cool the oil and garlic before drizzling it over the dip before serving.
Sprinkle with pul biber and fresh red chilli. Adorn with microgreens.
