I probably spend 50/50 on groceries and eating out. It's not great but I'm having a hard time budging those numbers.
8 minutes from the moment you walk in the kitchen, delicious Chinese fast food.
If you're really being honest about how much time it takes, you definitely need to include doing the dishes. And, yes, I can certainly go out and get food that fast. There are six bars and/or restaurants and/or coffee shops less than a one-minute walk from my front door, and with most you can call your order in and walk down and pick it up and come right back. (Or have it delivered if you're exceptionally lazy.) Welcome to urban life :-)
But that's not my problem with eating out. If I'm home, I eat home-made food. The problem is that there are a lot of days I'm just not at home between leaving for work in the morning and midnight. But I've yet to convince myself that saving $5 on a turkey sandwich grabbed on the way to something fun is worth having no social or cultural life outside the small apartment where I live alone. And the timing/distance/location just doesn't work for me to come home between getting off work and going out to do stuff in the evenings.
What I really hate is the way that healthy food costs a lot more when you are eating anything resembling fast food. You could eat incredibly cheaply in this town (probably cheaper than groceries) if you ate pizza, hot dogs, burgers, street cart food, etc. But for anything with a decent amount of vegetables you pay through the nose...
