Preheat the oven to 450°F. In a baking dish, toss together the pork, onion, peppers, garlic, oil, and vinegar, then season with salt and pepper. Bake for 20-25 minutes, until pork is cooked thoroughly to 150°F.
Serve pork with your choice of sides. You can roast a sheet pan of veggies while the pork is in the oven or serve with a side salad; and pair it with a wholesome carbohydrate of your choice, like baked sweet potato.
