Stuffed Spaghetti Squash is delicious, high in protein and lower in carbs. The squash is stuffed with a turkey bolognese sauce!

This is a go-to dinner for my fiancรฉ and I every fall and winter. It's very easy to make, super flavorful and cozy! I'm sure it will become one of your go-to recipes as well.
The bolognese sauce is what I like to call "semi-homemade" because I use jarred marinara sauce, but added in some additional ingredients.
I used Primal Kitchen's Roasted Garlic Marinara Sauce. If you want to purchase the sauce for this recipe, head to www.primalkitchen.com. Use code "frozenbananas" at checkout for a discount!
Why you'll love Stuffed Spaghetti Squash:
- Perfect weeknight meal - All you have to do is cook the spaghetti squash, make the sauce and marry the two!
- Flavorful - The sauce is bursting with flavor from the additions of the garlic, onion, carrots, celery and seasonings.
- Each serving has about 34 grams of protein!
- Comforting - In the colder months, you probably crave soup. If you're like me, you get sick of soup after a while. This is the perfect switch up!
- Lighter than pasta - Spaghetti squash is lower in carbs and calories compared to pasta. I haven't NOTHING against pasta, but sometimes you want something on the lighter side.

- garlic, onion, carrot and celery - These are the extras to upgrade the marinara sauce.
- ground turkey - You can use ground chicken or beef instead, if you'd like.

Recipe pro-tips:
- Cooking times will vary slightly depending on the size of the squash you're using.
- Be careful not to add too much salt! You may not need much salt at all since we are using store bought sauce for this recipe.
- I don't recommend using 99% lean ground turkey or it will be very dry. I use 94% lean.
Dietary adaptations:
- gluten-free - This recipe is naturally gluten free.
- dairy-free - Don't add the parmesan cheese.

Frequently Asked Questions:
Since spaghetti squash can be difficult to cut through at times, poke slits in the squash's skin with a knife (poke along where you will slice the squash in half.) Now, microwave the squash for about four minutes. It should be easier to slice through once microwaved.
Place the spaghetti squash on a cutting board. Slice through it lengthwise. Use a spoon to scoop out the seeds.
