First off, for the pesto – transfer the parsley, garlic, walnuts, parmesan, olive oil and lemon juice to a pestle and mortar. Grind until you have a rough paste. Add more olive oil if needed.
Next up, arrange the pulled apart bread on a baking tray and sprinkle with sesame seeds. Drizzle with olive oil and toast.
For the salad: Combine the tomatoes, feta cheese, crispy toasted bread and pesto in a mixing bowl – mix, season and serve.
