Heat 1 tablespoon of olive oil in a large skillet over medium heat.
Add pork and brown on all sides (you don't need to cook it through—you just want it nicely browned on the outside). Season with salt and pepper then transfer to a slow cooker.
Heat remaining oil in the skillet. Add onion, garlic, bell pepper and jalapeno. Cook until onion is translucent, about 5 minutes. Place sautéed veggies on top of pork then add salsa and broth.
Cover and cook on LOW for 6 hours or until pork is fork-tender. Remove pork from slow cooker and let it rest for about 5 minutes before slicing. Serve topped with slow cooker juices and enjoy!
