For the marinade, in a large ziploc or container, combine 3 tbsp each of olive oil and balsamic vinegar. Add pork and toss to coat, then refrigerate at least 4 hours, or overnight.
When you're ready to cook, preheat the oven to 425 degrees.
Remove pork from marinade, place it on a sheet pan, and season with salt and pepper.
Roast pork until internal temp reaches between 145 degrees (medium rare) and 160 degrees (medium), on a meat thermometer, about 25 - 30 minutes. Set aside to rest 10 minutes.
While pork is roasting, bring the bone broth up to a boil, add quinoa, cover and simmer for 15 - 20 min, until broth is fully absorbed. Fluff with a fork.
Cut pork into bite-sized pieces. In a large bowl, combine pork and any cooking juices with quinoa, cherries, scallions and almonds. Gently stir in kale, vinegar and olive oil. Add salt and pepper to taste, and more oil and vinegar if you like.
