Make sure you have a decent number of easy and healthy recipes on hand. While "bachelor food" as I call it, is by definition easy to make and tasty, it is also not that healthy and will leave you low on energy and feeling like a brick in the long run. I suggest finding a few things you can make regularly and maybe even setting up a weekly meal plan.

As an aside, my favorite bachelor dish is spaghetti with sauce, into which I grade so much cheddar the sauce turns orange. I also add ground beef if it is around. As with all bachelor food, eat it straight out of the pot if at all possible.
