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.

  • Reduce sodium: Use low-sodium or no-salt-added crushed tomatoes and Italian seasoning to cut down on the overall sodium content of the dish.

What can I prepare ahead of time?

  • Pre-slice the vegetables: Chop the onions and bell pepper and mince the garlic ahead of time. Keep them in separate airtight containers or ziplock bags in the fridge until you're ready to cook.
  • Pre-measure the seasonings: Measure out the Italian seasoning and any other spices you're using in advance. Store them in a small container to make cooking more streamlined.

Reheating best practices

    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!
