I created this recipe in October 2013 for a supper club dinner I threw featuring Mexican fall inspired recipes. This Mexican Stuffed Squash was the appetizer and my deliciously unique and amazing Pumpkin Enchiladas were the main course!

This recipe has been a huge hit ever since then with both my vegan friends and meat-eating followers. It’s so delicious and flavorful that everyone will love it!

The black bean corn relish and creamy avocado sauce are easy to whip up while the spaghetti squash is roasting. And if you have any leftover relish or sauce after making the stuffed squash, they both make great toppings for tacos, like on these Crispy Cactus Tacos, Vegetarian Avocado Tacos and Chipotle Honey Pulled Pork Tacos!

This recipe is PACKED with fresh ingredients. The spaghetti squash gives it the feel of fall, while the bright tomato corn relish will bring back fond memories of summer.

Anytime of the year that I can find spaghetti squash in season, I’m making this dish on repeat!

The first time I cooked this stuffed squash recipe to try it out, I ate half of a large spaghetti squash, which was plenty for lunch!

For the supper club dinner, I sliced each half of stuffed squash into three pieces and served that as an appetizer.

That’s the great thing about this dish, it can be served as an appetizer, lunch or dinner. It’s also gluten free, vegan, simple and so scrumptious!
