I know this sounds like a Dr. Seuss recipe (only without the elastic scansion) but it is, as the Italians say, "sul serio," no joke. The green factor is not crucial, but since this came about because I happened upon some spinach-dyed stubby coils of trottole—the pasta shape named after its supposed resemblance (I don't see it) to a spinning top—it feels right to me. Serendipity is only part of the story: I have also always had a thing about pasta and blue cheese, both separately and in conjunction. This recipe is in many ways an evolution of the Pasta with Gorgonzola, Arugula & Pine Nuts in my Quick Collection app, and indeed you could make any sort of mishmash of the two. The major developments here are that I felt the need—or rather a fancy—to sprinkle the deep green of the pasta with the paler pistachios, and I add no cream or mascarpone (as I used to) since a little pasta-cooking water, whisked into the cheese, makes it as creamy as you could wish for. This is not a dietary stance, but because the starchy water doesn't mute the palate-rasping piquancy of the Gorgonzola.
This colorful pasta dish has been on restaurant menus as far back as I can remember. Patrons love the two-tone pasta, crispy peas, prosciutto bits, and creamy sauce. Your family and guests will ask for second helpings every time.
Don't have a clue what to fix for dinner tonight? This dish is always a great solution to that problem. The tomatoes and parsley are the only fresh ingredients you need; everything else is probably in your fridge or pantry. For a splurge, use Spanish tuna in olive oil; for a bargain, try Genova brand, also in olive oil but half the price.
