Green pea soup

Ingredients:

• 1 (300 g) bag of frozen peas
• 1 teaspoon olive oil
• 1 large onion, chopped (about 1 1/2 cups)
• 2.5 tbsp. lightly salted chicken broth
• 3/4 tsp dried tarragon
• 0.5 tsp salt
• 4 tsp low-fat yogurt, optional

Preparation:

1. In a large saucepan, heat the olive oil over medium-low heat. Add the onion, cover, and cook, stirring occasionally, for about 5 minutes until softened. Pour in the broth, add the tarragon, salt, and a little black pepper. Bring to a boil. Then add the peas and cook until defrosted.
2. Blend the soup in two batches until smooth. If serving hot, pour the soup back into the pan and bring to a boil. If serving cold, refrigerate the soup. Then ladle into bowls, stir in the yogurt, and make yogurt swirls on the surface.
