I'm in a phase of coming off of eating lunch out almost every day. Like last week, for example. Today I brought lunch from home... but only because my wife made it for me. She can't all the time because she works too. Anyway, I'm trying to kick the eat out habit because it's too expensive. About $6 or $7 is my average lunch.
OUCH!
Anyway, it's a struggle. Eating out:
1) tastes good
2) is easy
3) gets me away from work for an hour
Today I had Progresso split pea soup, a ham sandwich, and a banana.
Also a suggestion: keep a microwave popcorn at work for emergencies.
