This silky-smooth lemon soup is based on the classic Greek avgolemono chicken and rice soup. We've turned it into a main course with the addition of Greek-style meatballs and spinach.
Heat the stock in a large pot. Bring it to just below a simmer, you don't want it to boil.
6 cups chicken stock
Add the meatballs to the stock and simmer for about 5 minutes to let them heat up and absorb some of the stock.
Greek-Style Lamb Meatballs
Combine the lemon juice and eggs in a bowl and whisk until it's smooth.
4 eggs, 2 tablespoons lemon juice
Whisk a couple of tablespoons of stock into the egg mixture. Don't add too much at once or you'll have scrambled eggs! Repeat until the egg mixture is just warm.
With the heat on low, gradually stir the egg mixture into the stock. You want a smooth consistency and a bright yellow color.
Add the spinach and orzo and stir to combine. Taste and add salt and pepper if you like.
2 cups cooked orzo, 5 ounces baby spinach
Heat gently until the spinach is wilted, about 5 minutes.
Ladle the soup into bowls. Serve with bread and a Greek salad.
