Fontina Chicken and Pasta Bake

Once again my cooking magazines have stocked up while I have battled some technical difficulties with my laptop and well, sometimes life just gets in the way.  This looks yummy although, not particularly friendly if you are watching your waistline.

1 16oz. pkg. spiral pasta
4 tsp. olive oil
2lbs. boneless skinless chicken breast, cut into 3/4 inch cubes
1/2lb. sliced fresh mushrooms
4 garlic cloves, mincs

1/2 tsp. pepper
2 6oz. packages fresh baby spinach, coarsely chopped
2 medium tomatoes, chopped

Preheat oven to 350 degrees.  Cook pasta according to package directions for al dente.
