Prepare the ingredients: Wash the split peas and remove impurities. Peel and slice the onion, garlic cloves, and celery.
Boil: Sauté the onion, garlic and chopped celery in olive oil until the onion is golden brown, and add the split peas. Boil the split peas in 1 liter of water over low heat for 40 minutes, adding a chicken stock cube, ground cumin, garlic powder, salt, and black pepper. Check the water level every ten minutes, adding one cup if needed, and stir occasionally to prevent sticking.
Blend: Use an immersion blender to blend the soup until smooth. Add the dill and mix. Remove any stringy bits of the celery. Serve hot, garnished with caramelized onion, alongside rice or fresh bread.
