Preheat the oven to 400 degrees.

Use a knife to cut down the center of each Italian sausage. Do not cut all of the way through the whole sausage.

Place a cheese stick into the hole in each Italian sausage, and try to fold the sausage back over it as much as possible.

Place 1 ¼ cups of low carb marinara sauce into the bottom of a baking dish.

Layer the stuffed sausages on top of the sauce.

Bake for 25-30 minutes until the sausages are cooked through and the cheese has melted.

Serve over a bed of salad, or with your favorite keto-friendly noodle substitute.
