This fast, creamy pasta combines bacon and mushrooms with the unexpected crunch of walnuts. Delicious! Any pasta can be used. Go without the bacon and skip step 3 to make this dish vegetarian- that's what we did & it was yum! I'd suggest perhaps doubling the sauce because we used only half of the pasta stated & found that there wasn't enough sauce to go with it - this *could* be because we used lite thickened cream, I'm not sure. This recipe comes from Australia's 'Delicious' magazine.
