Start by mixing the ground turkey, half of the finely diced green pepper, onions, minced garlic cloves, breadcrumbs, egg, salt, and black pepper in a large bowl.
Once everything is combined well, shape this mixture into medium-sized meatballs. Aim for about 12 meatballs from this quantity.
In a skillet, heat up the olive oil over medium heat. Place the meatballs and brown them on all sides. This should take about 2-3 minutes per side.
Once browned, transfer the meatballs to the Crock-Pot.
In the same skillet, add the remaining green pepper and sauté until it’s softened.
Add the tomato sauce, oregano, and half of the fresh parsley to the skillet. Mix well and let it simmer for about 5 minutes.
Pour this sauce over the meatballs in the Crock-Pot.
Cover and set the Crock-Pot on low heat. Let the Crock-Pot Turkey Meatballs with Green Pepper cook for about 4 hours.
After cooking, sprinkle the rest of the fresh parsley on top for a refreshing burst of flavor.
