  • 3 tablespoons olive oil, divided you will use 2 tablespoons for caramelizing the onions and 1 for the spinach
  • 1 ½ cups chopped onion
  • ¼ teaspoon salt
  • ¼ teaspoon sugar
  • 1 pork tenderloin They are usually in between 1-2.5 pounds
  • 4 cups fresh spinach
  • 4 ounces goat cheese


  • 1 tablespoon salt
  • 1 teaspoon garlic powder
  • ½ teaspoon black pepper
  • ¼ teaspoon paprika


  • Heat a saucepan over low heat.
  • Add in you olive oil and heat it as well.
  • Place chopped onions in the pan.
  • Stirring occasionally, cook them for about 10 minutes.
  • Sprinkle with about ¼ teaspoon salt
  • Continue to cook for another 5-10 minutes, stirring occasionally so it won't burn.
  • I sprinkled mine with about ¼ teaspoon sugar. You can skip this if you want, but I like it for better caramelization.
  • Once the onions are beautiful and caramelized, remove from heat and allow them to cool.
  • While they are cooling, let's saute the spinach.
  • Add 1 tablespoon olive oil to a pan and heat over medium heat.
  • Put in your spinach and cook for about 5-7 minutes until it is wilted. Make sure and stir occasionally.
  • Once both have cooled, let's start the pork.
  • Butterfly the pork. Once it is cut, I like to put it on a cutting board, then cover it with saran wrap. Pound it with the meat tenderizer until the pork is flat and the same thickness.
  • Combine the rub ingredients and mix well. Sprinkle about ⅓ of it on the cut side up of the pork tenderloin.
  • Spread the onions across the tenderloin, then the spinach, and lastly dot the goat cheese on.
  • Roll the pork up tightly and tie as shown in the photos.
  • Sprinkle with the rest of the rub and press it in.
  • Heat your grill over medium-high heat. Mine was about 400 degrees.
  • Cook the tenderloin for about 15-20 minutes. Making sure to turn it about 5 minutes.
  • Remove and allow it to sit for about 5 minutes. Cut off the ties. Then slice at about 1- 1 ½ inch.
  • This is best served right away. It reheats okay, but this will dry it out a little.
  • Now, sit back and enjoy. You deserve it!
