Love me some Trader Joe's, but I live in Long Island... so yeah.
We have one right around the corner from my office and we get a lot of our food staples there -- cereal, trail mix, pretzels, etc. They have a trail mix with dark chocolate, dried strawberries/raspberries, and nuts -- it's like freaking crack.
They also have some microwavable Indian food that's pretty decent for ~$1.25. Have that with some rice and their frozen naan, you're set for a cheap and easy bachelor meal.
