1 large onion(good for you)
1/2 cup dry red wine(good for the heart)
14.5 oz beef broth(low cal and low fat)
1 cup croutons(splurge...but I'm sure you could find a healthy version)
2 slices swiss cheese(I bought some that we're 60 calories a slice)
Heat 1 tablespoon olive oil over medium heat.
I'm off to the kitchen. Enjoy!
