Chef's pro tip
Be careful not to put too many sausages and vegetables in the skillet at once. If there's not enough room for everything to cook evenly, they might not brown nicely. If you need to, cook them in separate batches. That way, everything will cook just right, and you'll have a perfect meal.

Marci says
What do you eat with the sausage and peppers like a side dish?
Cast Iron Keto says
We typically do mashed cauliflower or a side salad.
Terry says
Is it possible to fix this and reduce the fat?
Cast Iron Keto says
Sure thing, simply reduce or omit the olive oil. The sausage gives off a lot of oil so if you're looking to cut fat, you'll still have enough in the pan for the veggies from the sausage. Hope this helps!
