After 20 minutes at 400 Fahrenheit it was clear that wasn't really working out so I removed the beans and put the bacon back in the oven for six more minutes.
I sliced up the beans and put them in a big skillet. They hadn't really picked up much flavor like I thought they would, so I seasoned them with salt, and added some sliced onion, and two cloves of minced garlic.
I sautéd this over medium high heat while the bacon finished. Then added the bacon, sliced, plus some of the bacon grease.
I lowered the heat, covered the pan, and let it cook another ten minutes. It was delicious.
I probably wouldn't do it exactly this way again, but the combo is good, so I would tweak it and do again.
