There are over 130 varieties of green beans, and most of them are dull dullsie dullsville...that is, until they're roasted. What is it about roasting vegetables that makes them taste amazing?
Trim a big pile of these weird little pods, getting rid of both ends of each bean. Yeah, it takes a bit of work, but presents a perfect opportunity for you to hone your knife skills! Use the edge to line them all up and hack off the ends. Perfection. Then, just like most of those other roasted vegetables I've presented (red peppers, beets, pumpkins, garlic, parsnips, potatoes, sweet potatoes, brussels sprouts...wow, that's a lot), toss them in salt and olive oil and bake for 30 minutes.
Let these guys get good and crispy. Eat them alone or throw them in another recipe, like Pad Thai. Yummers.
