Prepare the pasta according to package directions. Drain, reserving 1/4 cup pasta water.
While the pasta is cooking, in a large sauce pan or deep skillet, add the bacon fat over medium heat.
Add the diced and stewed tomatoes. Stir and bring to a boil.
Reduce heat and simmer for 10 minutes.
When the pasta is done, add the cooked noodles and stir to combine.
Let the macaroni and tomatoes simmer for an additional few minutes to allow the flavors to mix.
If the sauce is too thin you can add a little of the pasta water or a cornstarch slurry to thicken it.
Remove and serve. Garnish with fresh parsley and grated Parmesan cheese if desired.
Enjoy!
