>cooking is about US$10/meal give or take (asparagus, chicken, rice, water to drink).

You must be eating an absolute TON to eat $10 worth of chicken, asparagus, and rice. I just checked the prices at Target and rice is $1.89 for 2 pounds, chicken thighs are $1.69 a pound. Asparagus is spendier at $5 for 1 pound.

How many pounds of chicken and asparagus are you eating? Even if you ate two pounds of chicken and the entire pound of asparagus you aren't hitting $10.
