Lentils are a great filling for stuffed peppers because they’re easy to season and they add lots of protein and fiber to this meal. That means you’ll stay full and satisfied! I love how these stuffed peppers are full of flavor and the texture of the lentils is perfect in this recipe!

First, prepare the lentils and the rice. For a shortcut, you can used prepared or canned lentils.

Substitution Ideas

  • If you’d like to keep this recipe vegan, use vegan cheddar shreds or skip the cheese.
  • You can use brown or green lentils for the filling. Do not use red lentils, which are too soft.
  • To add even more flavor, try using my Mexican Brown Rice in place of plain rice.
  • You can use any color bell pepper you like. Red, yellow, and orange peppers will be slightly sweeter.
