Bring a large pot of water to a boil and cook the Elbow Macaroni as per the directions on the box. Once cooked, drain the pasta and reserve.
In the same large pot on medium heat, melt half of the butter. Place the celery and onion in the butter and cook them until the onions are translucent.
Add the onion powder, garlic powder, salt, and oregano to the cooking vegetables. Add in the canned tomatoes with their juices.
Let the tomatoes come to a simmer and let the juices reduce by about half.
Take the pot off the heat. Add the cooked pasta and the remaining butter to the pot with the tomatoes. Stir to combine and serve.
