We need this too - much like the OP, groceries are a bigger struggle for us than most other expenses.
Family size: two active adults, one 6yo
All three of us take lunches daily.
Have always meal planned and we have very little wasted food (!) but DH expends over 3,000 calories a day due to running and his on-his-feet job.
No special diets, but high on vegetables/fruits and buy higher quality meats. Vegetarian meals 50% of the time. We have fresh eggs from backyard chickens, and sell extra eggs to pay for the feed.
We do host friends often for wine/cheese or light dinners - I'd say ~4/month.
The "Grocery" totals include all groceries, alcohol, toiletries, household extras, etc. Shopping at Costco for bulk goods, local grocery for week-to-week and specialty store for local dairy consumed by 6yo. "Out" is all out-to-eat AND entertainment costs (like an occasional movie or function) which we lump together. Our family rule is that we don't eat out when its just us, but we do attend meals/ Happy Hour/ friend catch ups without much guilt.
2013 (Pre MMM) - Grocery Avg $780/mo, Out Avg $243
2014 - Grocery Avg $651/mo, Out Avg $152/mo
2015 - Grocery Avg $672/mo, Out Avg $142 - with the caveat that we hosted 6 extra adult family members for ~5 weeks of the year (who didn't pitch in food-wise). If I take out the extra family hosting, we spent $548/mo on Groceries.
Target for this year: Out $100/mo,Groceries $550/mo inclusive of any hosting friends/family. Extra gold stars if we can do $500/mo for Groceries.
