I found this recipe on the net. I love Olive Garden's Ravioli di Portobello, especially the sauce mmmmm. I have not tried this recipe, and I may be to lazy to make ravioli, unless I use wonton wrappers. I have seen premade mushroom ravioli before, so I plan to keep a look out and make the sauce to go with it. I look forward to trying it as soon as I see some ravioli. I am sure this sauce would be good on anything, including a leather boot, or tennis shoe if you are vegetarian! Enjoy! This recipe makes 15-20 ravioli. Timing is approximate.*UPDATE* Apparently the ravioli dough is no good, so I suggest using wonton wraps or your own dough recipe. I get the Barilla mushroom ravioli, and this sauce is absolutely wonderful.
