Ingredient notes

  • Bell peppers: Red, orange, or yellow are sweeter and preferable to green. Use a mix for a colorful presentation.
  • Walnut taco meat: This is the base of the filling. It’s recommended to use the walnut taco meat as written; mushrooms may be omitted if desired.
  • Beans: Black beans work well, but pinto beans or chickpeas can be substituted.
  • Corn: Fresh or frozen corn is fine—be sure it’s cooked or thawed before mixing.
  • Diced tomatoes: Fire-roasted diced tomatoes add depth of flavor; drain them before mixing.
  • Vegan cheese: Optional. Shredded vegan cheddar melts nicely if you want a cheesier finish.
  • Chipotle aioli: Optional garnish that pairs beautifully with these peppers. Prepare ahead if you plan to use it.

Step-by-step instructions

Step 1: Prep the walnut taco meat. Prepare the walnut taco meat first; it only takes about 10 minutes and can be made ahead to save time.

Step 2: Stuff the peppers. Slice each bell pepper in half and remove the seeds. In a bowl, combine the walnut taco meat, black beans, corn, and drained diced tomatoes. Stir in vegan cheese if using. Spoon the mixture into each pepper half, filling them generously.
