Unless Im eating Taco Bell, its much cheaper for me to cook at home in the long run. Even with current egg prices now, I can get a dozen eggs, English muffins or bagels, and cheese for like 5-7 dollars. Thats like a weeks worth of breakfasts. The same damn sandwich at Dunkin Donuts costs 5 dollars.
For dinner, I usually eat rice or pasta-based dishes. Good pasta dishes cost a helluva lot more, and if Im going to eat mediocre pasta, I dont want to pay for something thats twice the cost of the box of pasta and jar of sauce itself.
