Variations for Sauteed Mushrooms and Onions
- KEEP IT SIMPLE: Cracked peppercorn and sea salt
- TRY OTHER HERBS: Try adding fresh herbs like thyme, rosemary, dill and parsley. These herbs add varying flavors to your mushrooms as well as color. If you choose to use dried herbs, add in at the beginning so they have time to soften, but if you use fresh herbs, add near the end so they do not overcook.
- CHANGE UP THE FLAVOR: Instead of soy and sherry, try teriyaki sauce or even white cooking wine
