Preheat the Pot: Preheat a pot on medium-low heat. Drizzle the cooking oil, then add the sliced onion and garlic, and cook for 6 to 8 minutes.
Add spices and other ingredients: Add celery and green chili and cook for another 1 minute while stirring. Add ½ cup water and chicken stock to the pot. Also, add bay leaves, paprika powder, salt, pepper, and nutmeg. Stir to mix and cook for 2 minutes.
Add water: Add 3 cups of water and the potato. The potatoes must be completely submerged in the water. Cover the lid and cook for 15 minutes (while boiling) on medium-high heat.
Blend: Add the heavy cream and blend the entire soup with an immersion mixer. Garnish with beef salami, grated cheddar cheese, and fresh chopped parsley to serve.
