Wash the 3αλφα large chickpeas and soak them overnight in cold water. In the morning, we wash the chickpeas well under running tap water in a strainer. Put them between 2 clean cotton towels, and rub the towels together to remove peels. Transfer them to a large saucepan. Add water to cover them. Boil for 50 minutes, until completely softened. Then remove them from the pot and strain them.
Put a tablespoon of olive oil in a large nonstick pan and sauté the sweet potato cubes. Then add the boiled chickpeas and sauté for another 2 minutes.
In a small bowl, mix the tahini with the mayonnaise, olive oil, salt, pepper, juice and lemon zest.
Put all green vegetables on a large plate. On top add the sweet potato with chickpeas and tahini sauce. Gently stir and garnish with sesame seeds.
