Preheat oven to 350ºF. Halve squash lengthwise; scoop out seeds. Place squash, cut sides down, in a large baking dish and prick skin all over with a fork. Bake until tender, about 30 to 40 minutes.

2

Meanwhile, cook turkey in a nonstick skillet over medium-high heat until brown, about 5 minutes. Drain, remove from skillet and set aside.

3

In same skillet, heat oil over medium-high heat. Add onion and garlic and stir-fry for 5 minutes, or until tender. Stir in diced tomatoes and Italian seasoning; bring to boil. Reduce heat; add cooked turkey and simmer uncovered, 5 minutes, or until desired consistency, stirring often.

4

Place ricotta cheese and egg in food processor or blender and puree until smooth.

5

Coat a 9-inch glass pie plate with cooking spray. Remove squash from oven and increase oven temperature to 375ºF.

6

Using a fork, carefully rake stringy squash pulp from shell, separating it into strands that look like spaghetti. Arrange spaghetti squash strands in bottom and up sides of pie plate to form a crust.

7

Add ricotta cheese mixture and gently spread over squash. Pour tomato-turkey sauce over cheese mixture and sprinkle with mozzarella. Bake for 20 minutes. Remove from oven and let stand 5 minutes before slicing into 6 pieces.
