Have you heard about nut “meat” tacos? Well, these taco stuffed peppers are a fun new take on them. These veggie stuffed peppers are filled with taco spiced quinoa, black beans, pecan pieces, tomatoes and corn. Topped with avocado, salsa, or guacamole, a sprig of fresh cilantro and a squeeze of fresh lime juice, stuffed peppers are a flavorful and filling weeknight dinner, great to incorporate in weekly meal plans. We made these stuffed peppers even easier by cooking them in the Instant Pot. Let’s see how it’s done!

Instant Pot Quinoa

Step 1 in making vegetarian stuffed bell peppers is to cook the quinoa. The Instant Pot makes this very easy. If you’d prefer to make it on the stovetop follow the directions in this post all about cooking perfect quinoa. Cook the quinoa in the Instant Pot liner itself, or in a dish on the trivet, with one cup of water in the liner.

Vegetarian Stuffed Pepper Ingredients

The ingredients for this recipe are simple, and you might just have all of them in your pantry already. 

  • Raw pecan pieces for meaty texture 
  • Corn kernels for sweetness (fresh, frozen, or canned all work) 
  • Black beans 
  • Fire roasted tomatoes. You can also substitute salsa or enchilada sauce
  • Taco seasoning. Use one tablespoon for kid-friendly, and 2 for spicier. 
  • Fresh chopped yellow onion 
  • Chopped cilantro for freshness 

Nuts as a Meat Substitute

Though you might think of pecans as a dessert nut, they actually work beautifully in sweet and savory dishes. Fresh pecans are a source of plant-based protein, good fats, and fiber, which helps you stay fuller for longer*. They also have flavonoids and essential minerals, including copper, manganese and zinc. Their versatility makes them the perfect addition to your weekly grocery list – a bag of pecans can provide crunchy flavor and nutrition to any of your go-to meals.

Pecan pieces are a great substitute for ground meat. I love the hearty texture they add to tacos and these stuffed peppers.

How to Cook Stuffed Peppers in the Instant Pot

The Instant Pot pressure cooker makes tender stuffed peppers quick and easy, but if you don’t have an Instant Pot you can make them in the oven. Cut the tops off the bell peppers and scoop out the seeds with a spoon. Fill them up with the taco mixture and really pack it in. Add a cup of water to the pot and fit with the trivet or steamer basket. Place the stuffed peppers on top and pressure cook. 

For an even more kid-friendly option, top the cooked peppers with cheese (I use dairy-free) and pop under the broiler for a few minutes to melt. 

How to Serve Stuffed Peppers
