Cut your spaghetti squash into two halves. If you have trouble cutting it, pierce it with a fork and microwave it for 3-5 minutes on high. That’ll make it much easier to cut through. But, make sure to pierce it with a fork so that it doesn’t explode!
After cutting your spaghetti squash, remove the seeds and discard them.
Drizzle with olive oil and generously coat with salt and pepper.
Place them face down on a rimmed baking sheet, add a splash of water to the baking sheet, and cook for about 30-40 minutes or until the sides are easily pierced with a fork.
When the squash is tender and fully cooked remove it from the oven and set it aside.
For topping:
While the squash bakes, add a 12-inch skillet with 1 tablespoon olive oil over medium-high heat.
When the oil is hot add the ground chicken, bell peppers, onion, chili powder, kosher salt, garlic powder, onion powder, cumin, smoked paprika, cayenne pepper, and red pepper flakes.
Cook for about 10 minutes or until the chicken is cooked through and no longer pink.
Stir in the salsa and 1-1/2 cups of Mexican-blend cheese.
Remove from heat.
Fill the cavities of the spaghetti squash with the chicken fajita mixture, top with the remaining Mexican cheese blend, and return to the oven for ten minutes.
When the cheese on top is melted and browned remove it from the oven and top it with the desired toppings.
For serving:
Top each squash equally with sour cream, chopped cilantro, tomatoes, and lime wedges.
Serve and enjoy!
Notes
If your spaghetti squash is still firm after baking put it back into the oven for another 10 minutes, and add a splash of water to the baking sheet, depending on the size of your squash it may need additional cooking time. Remove it from the oven when you can push a fork into the skin easily.
If you can't cut through your spaghetti squash pierce the skin with a fork, and microwave it on high for 3-5 minutes, it’ll be way easier to cut!
