Whenever I think of pork and green beans Sichuan dishes come to mind.
Brown the ground pork in a healthy amount of smoking-hot canola oil (you want some excess). When it's browned, add some minced garlic, ginger, and fermented chile bean paste - stir it about until the oil turns red and the garlic is lightly browned. Toss the green beans in and stir-fry a bit. Add some water/stock and a shot of soy sauce, then cover to steam the beans. Thicken the final product with a bit of corn starch slurry and season with salt, white pepper, and a bit of sesame oil (use some ground sichuan peppercorn if you have it too).
Chow with white rice, spooning a bit of the chile oil over it.
