I eat half the box for lunch, the other for dinner.

I did not give a complete nutritional breakdown for the entire ingredients. The b vitamins you mention come from the chicken, which of course the pasta does not have, but I get many b vitamins in the soymeats I eat.

I did not calculate the broccoli, which is what many of the nutrients you listed come from.

I might mention that when I have my second half of the mac and cheese for dinner, I eat it with even more veggies, maybe carrots or cauliflower or brussels sprouts or a a mixture. This adds a scad more nutrients.

For dessert (because I not ultra-low carb), I may have some berries or a small apple or a small portion of another fruit. Throw in all the phytochemicals and nutrients from the fruit as well, and although I frankly don't have the time to add it up, I dare say the nutritional value would equal that of the dinner you mentioned.
