Is This A Freezer Meal?

Move the bag from the freezer to the refrigerator the day before you'd like to prepare in the slow cooker.
Preparing Slow Cooker Sausage Onion and Pepper
This is really so easy, it's almost difficult to post "steps".
First, stir together all ingredients in the slow cooker. Set to low for 6-8 hours. My slow cooker tends to cook on the hot side so I cook for 6 hours.
After the timer goes off, remove the cover and stir.
