Egg drop soup is so easy, here's one recipe that I use.
2 cups of Chicken broth
1 tsp dried basil
1 tsp dried parsley
salt and pepper to taste
1/4 cup chopped spinach
Heat the chicken broth in a small pot. Stir the eggs, basil, parsley and s/p in a separate bowl.
When the broth is hot, slowly add the egg mixture into the broth stirring gently with a fork. After about a minute, turn heat off and add chopped spinach.
