A ham sandwich is probably one of the poorest examples for this point. Ham has a fairly long shelf life, comes pre-cooked, and is exceedingly cheap as far as meat goes if you buy it on the bone when it’s available. Especially if you are willing to bake your own bread (I often see bread machines in many thrift stores), a ham and cheese sandwich is closer to $1 than $2.

1/5 lb of ham @$2.5lb is $0.50. A slice of cheese @ $2.50/lb is about $0.20. Two slices of homemade bread is about $0.20. I don’t know how much you’d add for vegetables or condiments but it ain’t much.
