This low carb stuffed vegan spaghetti squash is filled with seasoned zucchini marinara sauce and topped with a vegan cheese sauce for a healthy comfort food that’s also gluten-free, grain-free and vegetarian.
This is an easy stuffed spaghetti squash recipe that is loosely based on a vegan lasagna. Cooked vegetables with the marinara sauce and vegan cheese sauce all come together for a delicious main dish.
The biggest surprise of this dish was my husband's reaction. I thought he would not enjoy the flavors as he is not the biggest fan of spaghetti squash but one taste and suddenly I had to share. The second stuffed half I have planned to eat the next day disappeared!
