There are plenty of ways to get the nutrition you need so long as you don't go off on some nut-hatch guru preached "natural diet" or something. We have to eat, no way around it, so we might as well enjoy it to the max.

Now when I started being a vegetarian things looked grim. I was really concerned about getting enough protein and all the vegetarian literature said you had to have exactly the right mix of proteins at the same meal or they were worthless - and they recommended some pretty uninteresting dishes to assure that mix.

Of course it was bull byproducts all around. The then recomended dose of protein was dangerously high and was soon reduced but it's still way too high, and getting exactly the right mix at the same meal was more of the same. You've got around 8 hours and that's plenty.
