1/2 cup (2 oz) any hard cheese, shredded (I used cheddar)
4 oz feta cheese, crumbled
2 cups vegetables, sliced**
Cooking spray (I use Misto)
Preheat oven to 400 degrees F. Cut squash in half, scoop out the seeds and place face side down on a baking sheet lined with unbleached parchment paper. Poke skin randomly with a fork and bake for 30 minutes. Remove from the oven and set aside to cool until safe to handle.
Using a fork, separate spaghetti squash into strands and add to a medium bowl. Sprinkle with 1/4 tsp salt and mix. Using your hands, squeeze out liquid a bit. Return to the bowl along with 1/2 tsp basil and 1/2 tsp garlic powder; mix to combine. Spray deep pie dish with cooking spray and transfer squash into it. Press evenly on the bottom and sides using your hands. Set aside.
Preheat ceramic non-stick skillet on medium heat and swirl oil to coat. Add onion and bell pepper; sauté for 5 minutes or until golden brown, stirring occasionally.
In the meanwhile, add eggs, balsamic vinegar, 1 tsp basil and 1/4 tsp salt into previously used bowl and whisk. Add hard cheese, feta cheese, previously sautéed and fresh vegetables; stir well to mix. Pour into prepared crust and flatten with spatula
Bake in 400 degrees F oven for 50 mins or until the knife inserted comes out clean. Let quiche cool down for at least 30 minutes. Cut into 8 slices and serve hot or cold.
