Tomato egg drop soup

On most weekdays, I would cook soup using pork ribs or chicken in the slow cooker. Sometimes when I am really busy or tired, then I will go for quick soup recipes like this one I am sharing below - tomato egg drop soup. I am not exactly a tomato lover but this soup tastes really good. Simple and nutritious!  

Ingredients
Tomato
Egg
Bunapi mushrooms
Chopped spring onions (garnish)
Ikan bilis
Soya beans

Recipe
1. Wash the ikan bilis and soya beans and put them into the stock bag.
2. In a pot of boiling water, add the stock bag and let it simmer for 20 minutes.
3. Chop the tomato into cubes and remove the bottom from Bunapi mushrooms. Crack the egg in a bowl, beat it and set aside.
4. After 20 minutes, remove the stock bag from the pot. Add in tomato cubes, mushrooms and let it cook for a few minutes.
5. Taste the soup and season it with salt if you like. Pour in the beaten egg slowly and stir gently in circles using chopsticks.
6. Garnish with chopped spring onions and serve.
