Brighten your winter with this bright, lively soup that tastes like spring. It comes together in a flash, especially if you use store-bought broth, rotisserie chicken, and pesto.
In a saucepan, bring stock to a simmer. Add orzo and cook 1 minute less than per package instructions. Add chicken and heat through, about 1 minute. Remove from heat. Stir in lemon juice. Divide among bowls. Add 1 tablespoon pesto to each. Serve with lemon wedges, grated Parmesan, pea shoots or other delicate greens, and fresh basil.
