  • 3 cups fresh spinach
  • 3 tbsp olive oil divided
  • 3 lb pork loin or 2, 1.5 lb pork tenderloins
  • salt to taste
  • pepper to taste
  • 6 cloves garlic
  • 1/2 cup pepperoni slices
  • 1 cup Italian blended shredded cheese
  • 1 28 oz can crushed tomatoes
  • 1 small onion diced (about ½ cup)
  • 2 carrots peeled and diced (about ½ cup)
  • 2 cups diced potatoes red or yellow, skin on
  • 1 15 oz can cannellini beans drained and rinsed
  • 2 tsp garlic powder
  • 2 tsp Italian seasoning
  • 1/2 tsp crushed red pepper optional


  • Heat 1 tbsp of olive oil in large saute pan. Add spinach and cook, about 4 minutes. Set aside.
  • Place pork loin on cutting board. Butterfly the pork by slicing down the middle lengthwise about ¾ of the way through, being very careful not to go all the way through. Spread open like a book and pound with tenderizer until about 1.5 “thick.
  • Sprinkle both sides with salt and pepper. Evenly layer pork with cooked spinach, 6 whole garlic cloves, pepperoni slices, and cheese.
  • Roll up the pork lengthwise and secure by wrapping with kitchen string/twine. (You might lose some of your stuffing, simply stuff them back in once your pork is tied).
  • Heat remaining 2 tbsp of olive oil over medium-high heat in the same pan you used for the spinach. Add pork (seamed side down) and cook 3 minutes per side or until golden brown. Place pork in bottom of your slow cooker.
  • In medium sized bowl mix together crushed tomatoes, onions, carrots, potatoes, beans, garlic powder, Italian seasoning, and crushed red pepper.
  • Pour tomato sauce mixture over pork, cover and cook on low 8 hours.
  • Remove kitchen string, slice and serve.
