Straw and Hay Pasta
In a large stockpot, bring salted water to a rapid boil.
In a large saute pan over medium heat, add the olive oil and butter. When the butter is melted, add the onions and saute until translucent, but not browned, about 1 minute. Add the prosciutto and cook 1 more minute, stirring. Add the cream and bring to a simmer. Simmer until the sauce is just thick enough to lightly coat the back of a spoon. Season, to taste, with salt and black pepper. Add the peas and remove from the heat.
