Preheat oven to 400℉.
Cook pasta shells according to instructions on package.
While the shells are cooking, heat a large skillet over medium heat. Add the ground beef and saute until evenly browned about 2-3 minutes. Add in the onions, garlic, Italian seasoning, thyme, tomato paste, ½ cup of spaghetti sauce, salt, and pepper to taste.
Saute for 2-3 minutes more, then add basil leaves, spinach and cook until wilted.
When the shells and the meat sauce are cooked, place shells face up into a large casserole dish, place 1 ½ tablespoon of meat into the opening of each shell.
Then spoon spaghetti sauce on top. Sprinkle a combination of mozzarella and parmesan.
Bake in a preheated oven for 15 minutes or until cheese melts and starts to slightly brown.
Garnish with parsley, if desired. Serve warm.
