Notes
I divided this into 10 when I made this, but it was a ton of food, so I've changed it to 12 servings. For maximum efficiency, cook multiple things in parallel, AKA the bacon should be in the oven as the cauliflower is in the microwave as you are cooking the chicken and the sausage / vegetables. It might take a while the first time you make it but it will speed up a lot if you do these things in parallel.
