Add 2 tbsp olive oil to bottom of slow cooker

Add bag of frozen peppers & onions. Add italian seasoning to taste.

Add sausage links

Cover and cook on low 8 hours. Stir occasionally if you can but if not it'll be fine.

1 hour prior to them being done add jar of marinara sauce.

Serve on soft roll or over pasta. I add a slice of provolone before the sausage so it melts and then sprinkle with shaker cheese on top.
