Amp up the nutrition and make a well-rounded meal by serving with steamed or stir-fried vegetables like bok choy, broccoli, snap peas, or bell peppers (if you tolerate nightshades). You can add the vegetables directly to the skillet when making the beef or serve them on the side. A simple side salad like this Refreshing Cucumber Salad would also pair well. You can also serve Mongolian Ground Beef with steamed rice, cauliflower rice, zucchini noodles, or other vegetable noodles.
