Saucy Chicken Fajita Stuffed Spaghetti Squash - Electric Pressure Cooker Recipe

This recipe is Whole30 compatible.

  • 1 small spaghetti squash (washed well)
  • 1-1/2 lb boneless, skinless chicken thighs or breasts
  • 1 jar Mesa de Vida Smoky Latin Recipe Starter and Cooking Sauce
  • 2 bell peppers (any color) (cut in half vertically, cored and sliced into1/2” slices)
  • 1 large onion (peeled,cut in half, sliced into 1/2” slices)
  • salt and hot sauce/sliced jalapenos to taste (Mesa de Vida sauces are extremely low in sodium, allowing you to salt to your own tastes/preferences. If sodium isn’t a concern, I recommend 1 tsp for this recipe)
  • 1/2 cup water
  • Optional for serving: fresh chopped cilantro, hot cooked rice or cauliflower rice (to stay Whole30 compatible), hot cooked beans, shredded cheddar and/or cotija cheese
  1. Place the chicken, Mesa de Vida sauce, bell peppers, onion, salt and water into the Instant Pot, stir to combine. Add a piece of parchment paper over the mixture, then place the spaghetti squash on top. Cover, secure lid, and set the valve to “sealing”.
  2. Set the manual cook time for 15 minutes on high. Once the cook time is finished (it can take some time for the pot to come up to pressure, total time will be around 30-35 minutes), release the pressure on the valve.
  3. Carefully use large serving spoons to transfer the spaghetti squash to a platter. Let rest for at least 10 minutes before cutting.
  4. Meanwhile, hit the Saute function on the pressure cooker to boil the sauce, reducing the sauce by about half, until it coats the back of a spoon.
  5. After the squash has rested for 10 minutes, cut in half lengthwise. Scoop out the seeds, then rake the squash with a fork to separate into strands.
  6. Shred the chicken with two forks.
  7. Add the shredded squash back into the saucy chicken and vegetables, toss gently to combine. Serve, either in the hollowed-out spaghetti squash, or in a serving bowl.
  8. Optional: Top with cheese, allow to melt before serving.
  9. Enjoy!
  • Plant-based vegetarian version: Swap the meat for 3 cups (or 2 cans) of cooked black beans, rinsed and drained
