Mediterranean Lentil & Walnut Stuffed Peppers

A hearty plant-forward dish packed with fibre, plant protein, and heart-healthy fats.
These stuffed peppers are the kind of meal that quietly does a lot of good behind the scenes. Lentils bring fibre and steady energy, walnuts add satisfying richness and omega-3 fats, and the Mediterranean flavours tie everything together.
It’s simple, nourishing, and the kind of recipe that works just as well for a weekday dinner as it does for leftovers the next day.

Ingredients Method Notes

Ingredients
  

  • 4 bell peppers halved and seeds removed
  • 1 cup lentils cooked
  • 1/2 cup walnuts chopped
  • 1/2 cup cherry tomatoes diced
  • 1/2 tsp oregano dried
  • 1/2 tsp paprika smoked
  • 2 tbsp olive oil extra virgin
  • 2 tbsp feta cheese crumbled (optional)

Method
 

  1. Preheat the oven to 375°F (190°C).
  2. Place the halved peppers cut-side up in a baking dish.
  3. In a bowl, combine the lentils, chopped walnuts, cherry tomatoes, oregano, smoked paprika, olive oil, and feta cheese if using. Stir gently until everything is evenly mixed.
  4. Spoon the filling into the pepper halves.
  5. Add about ½ cup of water to the bottom of the baking dish. Cover the dish with foil and bake for 30 minutes.
  6. Remove the foil and continue baking for another 10 minutes, until the peppers are tender and the filling is lightly golden.
  7. Serve warm.

Notes

Notes for the Cook
  • Make it dairy-free: Simply omit the feta. The walnuts provide plenty of flavour and richness.
  • Add greens: Stir a handful of chopped spinach or parsley into the filling before stuffing the peppers.
  • Batch cooking tip: The lentil filling can be made a day in advance and stored in the refrigerator until ready to use.
Why This Recipe Works
This combination delivers a satisfying balance of nutrients:
  • Lentils provide plant protein and soluble fibre that supports stable blood sugar and digestive health.
  • Walnuts contribute omega-3 fats and minerals.
  • Bell peppers add vitamin C and natural sweetness.
Together they create a filling meal that’s both nourishing and satisfying.
