The cost of one meal's worth of peanut butter is just $0.60. That's pretty damn good! A peanut butter sandwich is $0.97. Even though Nutella costs significantly more than peanut butter, a peanut butter and nutella sandwich is only $1.16. That's probably a sufficiently small sacrifice for numiness :) So sandwiches are good.
Eating a meal made entirely of yogurt is $2 while it's on sale, and $3.20 normally. I was expecting it to be fairly expensive, but that's not too bad.
What kind of surprised me though was the meal i've been doing recently of tofu and salad. Even with the on sale salad bags it's $3.04, and that's before i've even figured out the cost of the dressing (probably around another $0.40 for that) and it still leaves me about 100-150 calories short of a full meal!
So it's actually cheaper to eat half of a $5 foot long sandwich from subway than to eat salad and tofu =P I'm sure i could theoretically reduce the cost of the salad by actually buying whole lettuce and shredding it myself, but i'd probably run into issues with spoilage that way, not to mention it being a pain. So after i go through my current supply of tofu and salad i should stop buying it, at least on a regular basis =P
For having put the effort into this research i'm going to reward myself by going to Subway :) (Does it still count as a reward if i'm saving money that way? =)
