Start with preparing your bacon as you normally would- either bake or pan fry to crisp

Allow to cool slightly & then rough chop or crumble into large skillet

In a large pot bring water to boiling & cook spaghetti to package directions (usually around 11 minutes)

Add garlic & seasonings to skillet with bacon & heat over low about 2 minutes - stirring frequently

In a medium bowl combine milk & cornstarch - whisk

Add milk mixture to skillet with bacon & cook on medium until thickened

Add Parmesan & cook until melted

Add cooked pasta to skillet & toss to coat

Season with salt & pepper & garnish with tomatoes & parsley before serving
