Ingredients
Makes 4 stuffed peppers.
- 4 large bell peppers (any color), tops cut off and seeds removed
- 1 cup cooked brown or green lentils
- 1/2 cup walnuts, chopped
- 1 small onion, diced
- 2 cloves garlic, minced
- 1 tsp dried oregano
- 1 tsp smoked paprika
- 1/2 cup tomato sauce
- 1 tbsp olive oil
- 1/4 tsp salt
- 1/4 tsp black pepper
- 1/4 cup fresh parsley, chopped (optional, for garnish)
Equipment
- Baking dish
- Large skillet
- Knife and cutting board
- Mixing bowl
Instructions
1. Preheat oven to 375°F (190°C). Lightly grease a baking dish and place the prepared bell peppers inside, cut side up. Choose peppers with flat bottoms so they stand upright.
2. Sauté onion and garlic. Heat olive oil in a skillet over medium heat. Add onion and garlic, cooking until soft and fragrant, about 3-4 minutes. Stir frequently to prevent burning.
3. Combine filling ingredients. Add cooked lentils, walnuts, oregano, smoked paprika, salt, and black pepper to the skillet. Stir in tomato sauce and cook for another 2-3 minutes until well combined. For extra flavor, toast the walnuts lightly before adding.
4. Stuff the peppers. Spoon the lentil-walnut mixture into the bell peppers, packing gently. Leave a little space at the top to prevent spillover.
5. Bake for 25-30 minutes until peppers are tender. Cover the baking dish with foil. Test doneness with a fork—it should pierce easily. Remove foil and bake for another 5 minutes if you prefer a crispier top.
6. Garnish and serve. Sprinkle with fresh parsley before serving. A sprinkle of nutritional yeast adds a cheesy flavor if desired.
Tips for Better Results
- For a spicier kick, add a pinch of red pepper flakes to the filling.
- Swap walnuts for pecans or almonds if preferred.
