1 onion, chopped
2 medium/1 cup tomatoes, petite diced

2/3 cup vermicelli/orzo
2 tbsp canola/olive oil
1 tbsp salt to taste
8 cups hot water
1 chicken bouillon (optional)
2 tbsp yogurt
1 egg

Saute onions with canola/olive oil in a pot for 2-3 minutes. Stir in tomatoes and continue sautéing over medium heat for a while. Add hot water, salt and chicken bouillon (if using). Once it starts bubbling, stir in potatoes and simmer over low-medium heat for about 10-15 minutes.
Stir in vermicelli/orzo. Cook for about 8-10 more minutes till the vermicelli/orzo and potatoes are cooked. Turn the heat off.
For the sauce, beat the egg and yogurt in a bowl. Take a ladle of soup and slowly stir in the sauce to reduce the heat difference between the soup and sauce. Then, slowly stir the sauce into soup. Sprinkle black pepper and serve warm.
