No, I couldn't, but when I eat a meatless dish as delicious as this mushroom ragout (pronounced ragoooo), I realize there are plenty of recipes that are just as tasty and satisfying as my favorite meat dishes. Of course, almost anything is good poured over garlic toast, and you'll see a great trick for ultra-fast and easy garlic-scented toast in this video recipe I recently produced for About.com. I did sneak some chicken stock into the sauce, but if you are a vegetarian you can use a vegetable stock and it will be fine.
Whenever I do a video recipe that uses Marsala wine I get lots of emails about what they can substitute. You can't, go get a bottle of Marsala wine. Just regular Marsala, not the sweet dessert Marsala as it is way too sweet to cook with. Ask the person at the wine shop to help you; tell them you are cooking with it and don't want the sweet variety and they will show you the right one. Buy the cheapest one of the selection they give you, and you're all set. Even the least expensive Marsala will be fine for this dish, as long as it's the real stuff, and came from a decent shop. Having said all that, if you must use something else a good Sherry wine (NOT the cooking sherry them sell at the supermarket) will fill in adequately.
