Spaghetti Squash Alfredo

1 medium spaghetti squash, cooked by your favorite
method and separated into strands
1 cup sour cream
1/2 cup shredded mozzarella cheese
1/4 cup grated Parmesan cheese
2 cloves garlic, finely minced
1/4 teaspoon salt
1/4 teaspoon black pepper

In a medium-size saucepan, combine all ingredients except
spaghetti squash over medium-low heat and whisk until smooth and
creamy, stirring constantly to prevent burning.

Add the spaghetti squash strands to the sauce and stir
until thoroughly mixed and heated through.
Serve immediately.

Serves 6 to 8.
