Ingredients
Instructions
- Adjust rack to top position and preheat oven to 425°F. Wash and dry produce. Halve bell peppers lengthwise; remove stems and seeds. Halve, peel and dice onion into ½-inch pieces. Drain and rinse lentils.
- Place bell pepper halves on a baking sheet and lightly drizzle each half with olive oil; rub to coat. Season with salt and pepper. Arrange cut sides down on sheet. Roast on top rack until tender, 10-15 minutes.
- In a small pot, bring couscous, half the stock concentrates and 1 cup water (2 cups for 4 servings) to a boil. Once boiling, cover and reduce heat to low; cook until al dente, 6-8 minutes. Drain any excess liquid if necessary. Keep covered off heat until ready to use in Step 5.
- Heat a large drizzle of oil in a large pan over medium-high heat. Add onion and sausage; cook, stirring and breaking up meat into pieces, until sausage is browned and cooked through, 4-6 minutes. Stir in marinara sauce. Bring to a boil then reduce to a simmer; cook until slightly reduced, 2-4 minutes.
- For Couscous Filling: Using a spoon, transfer half the sausage mixture to pot with couscous; stir to combine. Taste and season with salt and pepper. For Lentil Filling: To pan with remaining sausage mixture, add lentils and remaining stock concentrate; cook, stirring constantly, until warmed through, 1-2 minutes. Taste and season with salt and pepper.
- Once bell peppers are done roasting, remove sheet from oven; use tongs to flip bell peppers (careful-baking sheet will be hot!). Stuff bell pepper halves with as much couscous filling and/or lentil filling as desired. (Reserve any remaining filling for serving.) Evenly sprinkle mozzarella over pepper halves. Return to top rack and bake until cheese is melted and lightly browned, 4-6 minutes.
- Divide stuffed peppers between plates. Serve with any remaining fillings on the side.
Recipe Tips
For even roasting, make sure bell pepper halves are cut side down on the baking sheet.
If using lentils, be sure to drain and rinse them well before adding to the pan.
Customize each pepper: fill some with couscous mixture and others with lentil mixture for a mixed-diet meal.
