Spaghetti squash has a mild flavor and can be dressed up any way you like. Its high in fiber and low in calories, but with the right sauce it can be a satisfying meal unto itself. The sauce here is thick, hearty, and intensely flavorful. Although the roasting time makes this dish take around an hour, the hands-on prep is minimal, and I find spaghetti squash with creamy red pepper sauce makes a fine weeknight meal.
