I learned how to make this mixture from
Baked Salmon Stuffed with Mascarpone Spinach. I've always found that dish to be devine, but I generally don't make as much salmon as it calls for. Also, seeing as how mascarpone and soft cream cheese are sold at WinCo in 8 oz packages, I end up with 26 or more ounces after we get done with the spinach (I cheat and buy a package of the frozen chopped stuff). Making salmon doesn't take up nearly that much.
I find straight cream cheese a bit too rich, so mascarpone is perfect to thin that out while keeping it very nummy, and the spinach helps that, too. I'll eat this stuff straight out of the Tupperware. I've also made stuffed sauteed mushrooms with it and spread it on bread.
Just now I put it into a small burrito with black beans which I then pan fried in butter. MMMWONDERFUL.
