In addition to what others said, I buy 2 roast chickens a week for $5 each.

Rice is $20/25 lbs, and 1600 calories/lb for 2000 calories/$

They are 6.5lbs after deboning. Cooked chicken skin on is 950 calories per pound. That is 620 calories/$.

Tortillas themselves are 110 cal, and 4.99 for 100ct, or 2200 cal/$
