Red potatoes were 2, 5lb bags for $5, bought one for $2.50.
Pork chops were $1.29/lb, bought 5lbs for $6.45.
Peaches were $0.39 each, bought 6 for $2.34.
Romaine lettuce was $3 for a package.

Assuming that there are 10 potatoes to a 5lb bag, that's $0.25 per potato. I ate one last night, so that's $0.25. I ate 1/6 of a package of romaine, so $0.50. There were 8 pork chops in the 5lb package, so that's $0.80 per pork chop. I ate one peach, so there's $0.39.

That brings my total to a whopping $1.94 in money spent on last night's dinner. Add my wife's to that, and we almost spent $4.
