re: Family budget question re: groceries/food/consumables

Here's my best estimate as to where my "food" money goes. Note: I do all the grocery shopping, wife does the Wal-Mart/pharmacy shopping typically.

Family of 4 with two young kids. I’m averaging $847/month on fast food, groceries, restaurant eating, minor pharmacy stuff, and trips to wal-mart for misc toiletries and diapers. Anything that falls into that description comes out of the "food" bucket"

Usually don’t eat breakfast but keep cereal on hand (bag cheerios).
We do pretty well about not eating out for lunch but let’s say $20/week. (subway, fast food, etc…)
Throw in picking up supper one or two nights a week $45 (local pizza joint/po boy’s…)
Wal-Mart/CVS monthly for stuff ~$150
Maybe eat out once nice per month $100.
That’s ~$510 leaving me with $330 for groceries.

Typical weekly grocery list looks typically like:
Box or two of oatmeal $5
2-3 gal water $3
Gal of milk $5
~$15 meat (pork chops, pork tenderloins, chicken thighs, etc…)
Veggies/fruit $10
Lunch meat and bread $15
Eggs $3
Baby food/toddler food $10
Other Mist…
Total ~$75

Atypical grocery store pickups…
6 pack of beer
Steaks
seafood
Wine
Liquor

Typical weekly meals:
Grilled meats/fish
Kabobs
Tacos
Spaghetti
Grits and eggs
Reheated gumbo/soup/chili

So:
Eating out approx 15x per month ~$360
Wal-Mart/CVS ~$150
Groceries: ~$75/wk x 4 = ~$300
$30 to random meals
~$840 monthly
