For a vegetarian option, substitute vegetable broth for chicken broth. Add a squeeze of fresh lime juice just before serving for extra brightness. Consider topping with crumbled cotija cheese or a dollop of sour cream for added richness. To enhance the flavor, toast the quinoa with a clove of minced garlic or a small piece of diced onion before adding the broth. This dish pairs well with grilled chicken, fish, or your favorite Mexican-inspired protein.
