A popular side dish to accompany a Philly cheesesteak is fries.  French fries are usually served with the sandwich, but other fried potato dishes such as home fries and tater tots are also popular accompaniments.  To add some extra flavor, people often add condiments like ketchup or cheese sauce to their side of fries. Other vegetable sides for a Philly cheesesteak include roasted or steamed vegetables like carrots, broccoli, cauliflower, green beans, and mushrooms.  These can be prepared simply by roasting them with olive oil, salt, and pepper, or they can be seasoned with other herbs and spices for an added kick.  Another delicious side dish is a simple salad with crunchy lettuce, tomatoes, cucumbers, and your favorite dressing. In addition to vegetables and potatoes, there are plenty of other tasty sides that work well with a Philly cheesesteak.  For example, macaroni and cheese are always a hit as it pairs perfectly with the flavors in the sandwich.  Or you can try some cheesy breadsticks or garlic bread for even more cheesy goodness!
