Preheat oven to 350°F.

In a large bowl, combine cooked rice and pesto sauce; mix well.

Add cubed cooked turkey, finely diced tomatoes, sliced green onion, minced garlic, diced green bell pepper, chopped basil, salt, ground cayenne pepper, beaten eggs, and milk to the rice mixture.

Stir until all ingredients are thoroughly combined.

Grease a 9 x 13 inch pan.

Pour the mixture into the prepared pan, spreading evenly.

Top with shredded cheddar cheese and shredded mozzarella cheese.

Bake in the preheated oven for 20 to 25 minutes, or until a knife inserted into the center comes out clean.

Remove from oven and let cool slightly.

Cut into eight squares, then cut each square diagonally into two triangles.

Serve warm.
