A quick search has Walmart selling a 14.5 oz (411g) bag of Doritos for $5 [0], which according to the back of the packet is 15 servings. Obviously that's comparable to a single piece of beef and a potato (/s)

While we're at it, on the $5 Hershey's bar - Walmart has a 7.56 oz (214g) one for $4.52 [1] which claims to be eight servings so again obviously just like a single banana.
