Preheat oven to 200C.
Drain and rinse your chickpeas from the can. Add them onto a baking tray, add your seasonings and coat the chickpeas evenly.
Bake chickpeas for about 15-17 minutes until they are crispy, tossing them halfway.
Chop the ends of the leeks (there might be dirt stuck between the layers) and chop them nicely.
Peel potatoes and dice them into cubes. Smash the cloves of garlic with a knife.
To a pot, add vegan butter. Once it melts, add the leeks and saute for a few minutes. Add garlic and saute for a minute more.
Add your potatoes, 3 cups of water (2 cups if you want a thicker soup) and add your seasonings - vegetable stock cube, thyme, black pepper and salt (if needed).
Boil for 10 minutes until potatoes are fork tender.
Add in your soy milk and mix well. Use an immersion blender and blend the soup until smooth.
Top the soup with crispy chickpeas, olive oil and chives. Serve!
