I had an aphid infestation on some bean plants that resulted in stunted vines and the same type of deformed leaves.

That definitely looks like an aphid problem to me.

Really? Aphids?

Why are they only attacking this one plant?

I noticed these weird flies out there when I went to get this second pic...

The flies are small, and metallic looking in the sun.

Weird.

Looks like leaf stress disorder. When environmental conditions (amount of water, temperature, light) suddenly change, a number of plants will exhibit distorted new growth like that. Once the conditions stabilize, any subsequent new leaves should develop properly.

Meteor, several of mine are doing that too, along with some of my basil plants. I'll try and get some pictures after it cools down a bit outside.
