Heat oven to 375 degrees Fahrenheit.
Mince 6 cloves of garlic and 1 small onion (any color).
Cut 1 jalapeno pepper in half and remove the seeds and membranes for less heat. Finely dice the jalapeno pepper.
Roughly chop 3 packed cups of kale (curly or lacinato kale). Feel free to use any hearty greens, such as spinach, Swiss chard or collards in place of the kale.
Drain and rinse 1 can of black beans to remove any excess salt (feel free to sub Pinto beans or beans of choice).
Cut 4 large bell peppers lengthwise into halves. Remove the stem, seeds, and membranes from each of the peppers and discard.
Place a large skillet on the stove top and heat to medium-high. Add 2 Tbsp. olive oil to the skillet. Once heated, add the minced garlic, onions, and jalapeno. Sauté for 4-5 minutes, stirring often. Add 1 lb. lean ground turkey to the skillet, along with 1 tsp. each kosher salt and pepper, 2 tsp. each smoked paprika and chili powder, and 1 tsp. each ground cumin and dried oregano (or Italian seasoning). Sauté the ground turkey for 8-10 minutes on medium-high, breaking it apart with a spatula as it cooks.
Add the chopped kale (or hearty greens of choice) to the skillet and cook until the kale has wilted down slightly. Add the can of drained and rinsed black beans (or beans of choice) to the skillet and stir until combined.
Sauté all of the ingredients for another 1-2 minutes, stirring until completely combined. Remove the skillet from the heat and set aside.
Pour 2 cups of gluten free red enchilada sauce into the bottom of a 9x13 inch baking dish. Arrange the bell pepper halves on top of the sauce in the baking dish. Spoon a generous amount of the filling into each of the bell pepper halves. Continue until all the filling is used (it will likely spill over the peppers). Cover the baking dish tightly with tinfoil and bake for 30 minutes.
Grate 1-2 cups of Pepper Jack cheese (or cheese of choice). After 30 minutes, remove the tinfoil and sprinkle 1-2 cups of the shredded cheese (depending on how much cheese you like) over the top of the peppers.
Return the baking dish, uncovered, to the oven and bake for another 15 minutes.If you find that the bell peppers are still too crunchy at the end of the cooking time, feel free to return them to the oven until they reach your desired level of softness. To Serve: Serve stuffed peppers with a squeeze of lime juice. Garnish with fresh cilantro and sliced avocado (optional).
