If You Usually Order:
Chicken Parmesan with a side of spaghetti.
Make It Healthier:
Try grilled chicken on top of pasta. And go local when you can. A mom-and-pop restaurant is more likely than a chain to prepare food the healthful and traditional Mediterranean way (read: less processed).
If you crave pasta, avoid cheese-stuffed varieties (better yet, ask for spaghetti squash), and top it with marinara sauce (as opposed to anything cream-based). As for meat, choose a chicken or fish dish that isn't fried.
