1 tablespoon olive oil
1 medium onion, finely chopped
2 cloves garlic, minced
1 pound chicken breast, cut into bite-sized pieces
4 cups chicken broth
2 large carrots, peeled and sliced
1 bunch of watercress, roughly chopped
Salt and pepper to taste
Optional: a squeeze of lemon juice for added zest
If you prefer a clearer broth, you can strain the soup before adding the watercress, ensuring a smoother texture.
