I used to pack a lunch - nothing fancy, just a couple of sandwiches, & maybe fruit - then cook dinner, all for around $100/week. Started treating myself to bought lunches. Again nothing fancy, mostly fast-casual type places where you order at the counter & they bring your food to the table. Water not soda. Restaurant lunches are cheaper than restaurant dinners, but they’re also way more calories than my packed lunches, and I found I wasn’t in the mood for big dinners anymore. In the end, I was still spending around $100/week, eating out 5 days/week, and just having a snack in the evening.
