We night owls already knew that, and poo-poohed those studies.
But, for dinner, there is something special ... and healthy ... at least if you dine at my place ... and it's inexpensive, too. Just made:
Sun-dried tomato alfredo (Classico jar), supplemented with fresh Asiago cheese, grated Parmesan and butter (all melted together, then added to the alfredo in the main pot), fresh ground black pepper, and basil, served over the usual whole wheat pasta, plus green beans and broccoli, and artichokes, plus diced pork loin and a touch of diced pepperoni.
I use just enough on sauces to coat, not drown. All quite healthy, with the fiber, and no added salt. There’s enough in the pasta sauce jar.
