Preheat oven to 400 degrees F.
Cut the spaghetti squash in half lengthwise and remove all of the seeds. Season with olive oil and a pinch of salt and pepper.
Roast face down on a baking sheet for 35-40 minutes, or until tender (also depends on the size-I roasted for about 37 minutes).
While the spaghetti squash is baking - in a bowl, combine cream cheese, 2 tbsp cheddar cheese, greek yogurt, jalapeno, and most of the chopped turkey bacon (reserve the rest for topping), chili powder, garlic powder, and a pinch of salt and pepper.
When spaghetti squash is done roasting, loosen up and fluff the strands. Divide the cream cheese/jalapeno mixture evenly in each half of spaghetti squash. Pull the strands again to mix everything.
Top with the rest of the chopped turkey bacon and 2 tbsp shredded cheddar cheese. You can also add a few jalapeno slices. Bake for another 10-12 minutes. Top with chopped green onion.
Serve immediately and enjoy!
