For the meatballs:

  • 1 lb ground beef
  • cup almond flour
  • ¼ cup parmesan cheese
  • 1 egg
  • ¾ teaspoon black pepper
  • ½ teaspoon Himalayan pink salt
  • ½ teaspoon dried parsley
  • ¼ teaspoon dried basil
  • ¼ teaspoon garlic powder
  • ¼ teaspoon onion powder

For the subs:

  • 1 jar Marinara Sauce
  • 4 bell peppers stems removed and slice horizontally in half
  • 4 slices provolone cheese


  • Preheat oven to 350 degrees F.
  • In a large bowl, add meatball ingredients and combine using clean hands. Form the mixture into 16 meatballs.
  • Add a tablespoon of olive oil to a large skillet on medium-high heat. After the pan is heated through and oil is hot, add all of the meatballs and cook for 10 minutes - turning them every few minutes to ensure equal browning.
  • Turn the heat down to medium-low and pour the jar of marinara sauce over the meatballs. Cover and simmer for an additional 10 minutes.
  • Place bell peppers (cut side facing uon a baking sheet. Drizzle with olive oil and sprinkle salt and pepper. Place a piece of provolone on four of the pepper halves and place in the oven for 7 or so minutes to allow the cheese to melt.
  • Remove the peppers from the oven, and add 4 meatballs on top of the cheesy pepper halves. Sprinkle with additional parmesan cheese if desired. Top with another bell pepper half to finish the sub sandwich. Enjoy warm.
