  • 1 pound ground sausage
  • 1/2 tablespoon avocado oil (or more if needed)*
  • 1 1/2 pounds yukon gold potatoes, diced into 1/2-1 inch pieces**
  • 1 1/2 cups thinly sliced onion (150 grams)
  • 5 cups diced peppers (600 grams) (I used red, yellow, and green)
  • 1 tablespoon Italian seasoning
  • 1 1/2 cups marinara sauce
  • 1/2 cup packed shredded mozzarella cheese (2 ounces)
  • salt and pepper, to taste
  • optional toppings: fresh basil, fresh parsley, red pepper flakes....


  • Heat a large cast iron skillet over medium heat. Once hot, add ground pork with a little salt and pepper and break it up with the back of a spoon. Sauté for 5-7 minutes until browned and cooked through. Remove from pan, leaving the grease behind, and place in a bowl.
  • There should be some leftover pork grease in the pan. Add avocado oil and let it get hot.* Add potatoes with a little more salt and pepper and cook for 10-15 minutes until browned and almost cooked through. I covered them with a lid and added a little water every so often to the pan to help speed up the process. When the potatoes are geting close to being done, add onion and saute for another 5 minutes.
  • Add the peppers with the Italian seasoning and saute for 5-7 minutes until softened. Add the pork back in with the pasta sauce and mix well to combine. Let everything warm through, about 1-2 minutes. Top with the shredded cheese let it melt, about 1-2 minutes. Top with fresh herbs if using and enjoy!


*if you have enough grease left behind, you might not need any oil. You might need more oil than suggested if you don't have any grease.
**the smaller and more uniform you dice the potatoes, the faster and better they will cook.
