Yes, the more natural you eat, I think the better off you'll be.
As a bachelor, consider frozen vegetables. Freezing them often locks in the nutrients and in SOME cases, they can be better than what is sold as fresh. Of course your mileage may vary.
When I was a bachelor, I did the crock pot thing, I also used my George Foreman grill to grill up a chicken breast to go along with my vegetables. Or when it was warmer, I'd fire up the outdoor grill and do 4-6 breasts and use them throughout the week.
You can mix them in a salad. Don't be afraid to put some fruit in your salad too, such as dried raspberries or orange slices with a healthy side of dressing.
I don't soak my food in dressing but put a single serving on the side and dip my fork in the dressing before I take a bite of the salad. I typically don't even use a whole serving of the dressing.
It's about finding balance, and using moderation.
Then again, sometimes I simply crave those chocolate frosted donuts
But if that's a once or twice a month thing, instead of daily, it's probably not going to kill me.
