Add milk and water to a medium-sized pot on medium heat.
Once the milk is hot but not boiling, turn the heat down to low and simmer. Don't allow milk to boil.
Add in the green onion, cilantro, and garlic and stir.
Crack an egg into a small bowl and then carefully add egg to the pot. Repeat with remaining eggs.
Sprinkle the bread and cheese on top.
Simmer for 3 more minutes or until eggs are at desired doneness (we like cooked whites and a jammy yolk).
Add salt to taste and stir one more time.
Scoop soup into four bowls, trying to get egg, cheese, and bread evenly divided into each bowl.
