Eggs are great for a quick protein fix during pregnancy, boasting more than a dozen vitamins and minerals in a small-but-mighty package. Whisk them into a simple frittata and load it up with lots of veggies, such as pleasantly bitter Swiss chard and sweet red onion. A little faux bacon and a sprinkle of feta make it feel indulgent. To be on the safe side, make sure that the cheese is pasteurized.
