Prep the ingredients
Wash and chop all the vegetables. Soak the quinoa and brown lentils separately for at least 1 hour, then drain and set aside.
Start the veggie base
Place a deep pan or pot over medium heat. Add chopped garlic and sauté until fragrant. Add chopped onions and cook until translucent. If the mixture starts sticking (since it’s oil-free), add a few tablespoons of water.
Build the flavor
Add chopped carrots and celery. Cook for a few minutes until slightly soft. Then add zucchini, cilantro stems, and jalapeños. Let everything cook for 2–3 minutes until the zucchini softens and the herbs release their aroma.
Cook the lentils
Add the drained brown lentils to the pot. Pour in enough water to cover them and cook until the lentils are soft and tender, adding more water if needed.
Add the quinoa
Once the lentils are cooked, add the soaked quinoa and just enough water to cover it. Cook until the quinoa is fully done and all the water is absorbed. The mixture should be moist but not watery since it will be used as stuffing.
Season and finish the filling
Add chopped walnuts, chili flakes, Italian seasoning, and salt. Mix well and let everything simmer until the mixture is completely dry and well combined. Turn off the heat and allow the stuffing to cool.
Prepare the bell peppers
Cut the tops off the bell peppers and remove the seeds and membranes from inside. Keep the tops aside.
Stuff the peppers
Fill each bell pepper generously with the lentil-quinoa mixture. Place the stuffed peppers in a baking dish and cover with the pepper tops.
Bake
Bake at 400°F (200°C) for 20 minutes. The tops cook faster, so remove them halfway if needed to prevent burning.
Serve
Serve hot with my Green High Protein Sauce for a creamy, high-protein, flavor-packed finish.
