Let me calculate whole grocery cost/month.

Breakfast:
60 eggs/month = 5 dozen brown eggs = 5 x $3.00 = $15.00
Beacon 60 slice = 10 Lb = $ 50.00
Banana = 30 units = 0.50 x 30 = $ 15.00
Blueberry = $1/day = $ 30.00
Milk 8 gallon/month = $ 32.00
Oatmeal = $ 15/month
Coffee 4 pack a month = $ 40.00
Total break fast = $ 197.00

Lunch:
$ 9.00/day (most buffet lunch menu cost same)= 20 days work x 9 = 180.00

Dinner:
Basmati Rice $1/lb/day = $30.00
Vegetable $1/day = $ 30.00
Meat 1/2 Lb / day = 30 x $ 2.00 = $60.00
Spices $ 30/month
Total cost = $(197+180+30+30+60+30) = $ 520.00 approx

There is trade off. If you eat at home, you don't eat lunch outside and vice versa.

$900.00 food cost/month is quite high, unless you eat steak, seafood, pizza, gyro, fast food regularly.

Note: This is not my monthly plan.

Utilities is part of rent.
