Ingredients

  • 1 ¼ to 1½ pounds pork tenderloin cut into ¾ -inch chunks
  • Kosher salt and pepper to taste
  • 2 tablespoons cornstarch
  • 3 tablespoons avocado oil or olive oil divided
  • 1 red bell pepper chopped 1-inch pieces
  • 1 green bell pepper chopped 1-inch pieces
  • 1 medium yellow onion chopped 1-inch pieces
  • 2 teaspoons grated ginger or ginger paste
  • 1 clove garlic minced
  • 8 ounce can pineapple chunks drained, juice reserved

Light Sweet and Sour Sauce

  • Pineapple juice reserved from the can, about ¼ cup
  • ¼ cup Low sodium broth or water or as needed
  • 3 tablespoons rice vinegar or apple cider vinegar
  • 2 tablespoons low-sodium soy sauce or tamari for gluten-free
  • 3 tablespoons ketchup
  • 1½ to 2 tablespoons honey
  • 1 tablespoon cornstarch

Instructions

Prep and brown the pork

  • Place the pieces of pork in a medium bowl. Season to taste with salt and pepper and toss with 2 tablespoons cornstarch until the pork is well coated.
  • Heat 2 tablespoons of oil in a large nonstick skillet. Sear the pork for about 3 minutes per side until lightly browned and cooked through. Transfer to a plate.

Make the sauce

  • Strain the pineapple juice from the can into a small bowl. Add the vinegar, soy sauce, ketchup, honey, and cornstarch and whisk until well combined. Set aside.

Cook the veggies

  • Add the remaining 1 tablespoon oil to the same skillet and return it to the heat. Cook the onion and bell peppers for 5 to 6 minutes until crisp-tender. Add the garlic and ginger and cook for an additional 30 seconds.
  • Add sauce and pineapple
  • Whisk the sauce to be sure the cornstarch is well incorporated and pour it into the skillet. Add the pineapple chunks and bring the mixture to a simmer. Cook for 1 to 2 minutes until the sauce is thickened and glossy.

Finish and Serve

  • Add the cooked pork and simmer for 2 to 3 minutes, until warmed through.
  • Served spooned over brown rice or cauliflower rice.
