Well, for a tiny bit of context, Wally, I am on a zero carb, limited  
protein kick this week.  Here's my budget:

$24 of grassfed lamb (5.3lbs)
$6 avocados
21 eggs = $3.75
7 slices bacon = $4
salt = 10c
magnesium/potassium = $1
garlic = $1

total $39.85

So about $40 for a full week -- or $28.50 for five days.  No where  
near $15 for two, but not hard on the wallet at all.
