Add ground beef to pan and season with salt and pepper. Cook over medium-high heat, stirring often to break it into crumbles and brown on all sides, about 8 to 10 minutes.

Remove from pan into a bowl, drain excess grease if needed and set aside.

Add diced tomatoes, sugar, shallot and butter to pan and bring to a boil. Lower heat and cook 20 minutes, stirring often.

Return browned ground beef to the pan with the tomatoes, stir in Parmesan, half and half and tortellini. Raise to medium heat and cover with lid. Cook for 5 minutes, stir well, lower heat to medium-low and cover. Cook an additional 5 to 8 minutes or until tortellini are heated through.

Stir in fresh basil and serve immediately.
