Preheat oven to 350℉
Bring a large pot of water to a boil. Cut the tops of the bell peppers off and remove the seeds. Boil the peppers for 10 minutes until they are soft. Remove from the pot of water and set aside.
In a pan over medium heat cook the ground beef until fully cooked. Remove from the pan and set aside.
Add one tablespoon olive oil to the same pan and add the minced garlic. Cook for 2-3 minutes. Cut the zucchini and add it to the pan. Cook until softened about 10 minutes.
Add the cooked beef back into the pan and mix together the taco seasoning, paprika, garlic powder, salt, pepper, and half and half until everything is fully mixed together. Fold in the beans.
Place the peppers in a baking dish and evenly fill each pepper with the beef mixture. Top with shredded cheese.
Cook until the cheese is bubbly and melted between 7-10 minutes. Let cool for a few minutes before serving.
