I live next to a wholefoods and a wegmans so this is a good comparison. The things I buy bring my average meal cost to about $5. If I eat out (chipotle or something) it is $10.

I eat simply. One thing I love is wholefoods preseasoned chicken. It's about 2.99 a pound and serves 3 meals (2 dinners, and my lunch for the next day).

I should also note I eat around 3100 calories per day.

edit: I should also note. cooking for more than 1 meal at a time brings my average cost per meal down quite a bit. Even if it is only 2 meals.
