Quinoa is one of the only complete proteins in the plant world. Make it a meal with tender shrimp, buttery avocado, and a slurry of fresh green herbs. Shrimp is a safe seafood choice for pregnancy, as it’s low in mercury. Grilling the shrimp adds a layer of sweet, smoky flavor. Often thought of as a grain, quinoa is actually the seed of a green vegetable related to spinach, beets, and Swiss chard. The main varieties are white, red, or black – all are good choices.
