We recommend a wild rice medley. However, check the packaging instructions on how long to cook the rice. Wild rice cooks much longer than most other types. 
You can cook the rice in chicken or vegetable broth/stock, or just water. If using water, you'll only need 1 cup of broth/stock for this recipe. Also, you can substitute Swiss or Gruyere cheese for the Fontina.
If using frozen spinach, allow it to thaw completely first and then squeeze as much of the water out of it as possible. 
The casserole can be assembled 1 to 3 days before baking. Cover with plastic wrap and keep in the fridge until ready to bake (if chilled, you may need to bake it an extra 10 to 15 minutes - keep an eye on the almonds, if they are getting two brown, cover with foil.
Leftovers will keep covered in the fridge for up to 5 days. Reheat in the oven (350°F) until heated through, or heat in the microwave on HIGH in 1-minute intervals.  The casserole can be frozen for 2 to 3 months. Let thaw completely before baking.
