Substitutions For Low Carb Buffalo Chicken

Here's substitutions you can make for this recipe. Remember that when you make substitutions, it will change the nutritional data you see below.

Chicken - Substitute shredded turkey. Ground chicken or ground turkey would work too - I recommend cooking ground meat with the veggies. Tempeh or tofu could also be easily substituted here.
Cauliflower Rice - I recommend frozen cauliflower rice for this recipe. If you don't like cauliflower rice, broccoli rice works instead. Quinoa or brown rice could be substituted, but I would recommended adding those things pre-cooked as I have not tested how long that would take to bake in the casserole.
Buffalo Sauce - Any hot sauce you like works. If you like things less heat, reduce the quantity and replace some with broth.
Egg Whites - You can omit. Some of you will ask if you can use whole eggs - yes, you would substitute ONE whole egg. HOWEVER, this will decrease the protein and increase the overall calories.
Greek Yogurt - Any dairy free yogurt substitute will work.
