Bring a small pot of salted water to a boil and cook the whole wheat penne according to package directions until al dente.
While the pasta cooks, heat a large non-stick skillet over medium-high heat and add the ground pork, breaking it apart with a wooden spoon.
Cook the pork until thoroughly browned and no longer pink, then remove the meat from the pan and set aside, draining any excess fat.
In the same skillet, add the water, diced onion, finely diced carrots, and minced garlic, sautéing until the vegetables are softened and fragrant.
Return the cooked pork to the skillet and stir in the tomato puree, dried oregano, sea salt, and black pepper.
Lower the heat to a simmer and cook the sauce for 5-7 minutes to allow the savory flavors to fully develop.
Drain the pasta and toss it directly into the skillet with the pork ragu until every noodle is well coated.
Garnish the dish with freshly chopped parsley and serve immediately.
