Substitutions
- Ground turkey- Use ground turkey instead of Italian sausage for a healthy alternative.
- Minute rice- In a pinch, because you cook the rice beforehand, minute rice works wonderfully with this recipe.
- Cauliflower rice- At a 1:1 ratio, substitute cauliflower rice for the white rice for a vegetable heavy dish.
- Quinoa- Looking for more protein? Use quinoa at a 1:1 ratio instead of rice.
- Brown rice- We love brown rice! This recipe uses white rice, but brown rice can easily be used instead.
- Cheddar- Have a thing for cheddar cheese? Use shredded cheddar cheese instead of mozzarella.
Variations
- Spicy - add a couple of chopped jalapeño peppers to spice this dish up!
Equipment
- Mixing bowl
- 9x13 baking dish
