I happen to live alone and make a small batch of this pasta that's perfect for two (or one, with leftovers). For a family of four, simply double the recipe below. Adding the hot pasta on top of the arugula is critical as it helps in wilting and softening the greens.
1/4 pound fettuccine
2 tablespoons unsalted butter, softened
1/4 cup freshly grated Parmesan cheese
1/4 cup heavy cream, warmed
1/3 cup pine nuts, toasted
3/4 cups arugula
1/4 cup freshly cooked peas
1/4 cup shredded prosciutto
Kosher salt and freshly-ground pepper
Lay the arugula on the bottom of a medium-sized serving dish.
Place the fettuccine in a boiling pot of water and cook until al dente. Pour into a colander to drain. Pour drained pasta on top of the arugula and add the warm heavy cream, butter, and Parmesan. Stir quickly to combine and wilt the arugula leaves.
Add the peas, pine nuts, and prosciutto and toss until well mixed. Season with kosher salt and freshly ground pepper. Serve while piping hot.
