i disagree on the hold the cheese aspect but I'm a known dairy heretic.
the problems with pizza are:
- pizza crust is pure white flour, unless you can find some sort of whole wheat crust (multigrain and other options may or may not cut it, and it may be hard to get a handle on just how much fiber is really in it)
- my favorite topics, at least, are all high in saturated fat, sodium, and nitrates (pep, sausage, bacon)
- if the cheese is not at least part skim, it tends to magnify the above
you're looking for self-improvement? figuring out how to cook for yourself, in whatever circumstances, is probably the best thing you can do for your health, especially as a first year college student. you've got (at least!) 3.5 more years, and you're setting up habits that will be very hard to break in the future. you'll always feel pressed for time, from now until (and maybe after) retirement. maybe my expectations are unreasonable, but i expect even crappy dorms to have at least one kitchen. now, finding the discipline to seek it out regularly is another story.....
