Spaghetti Squash with Roasted Red Pepper Relish and Walnuts

It’s not pasta! It is Spaghetti Squash with Roasted Red Pepper Relish and Walnuts. It’s Meatless Monday perfection, as well as being delicious, gluten-free and vegan, too. 

This recipe is actually two recipes. I have topped the spaghetti squash with Roasted Red Pepper Relish. In addition to being fabulous atop this dish, Roasted Red Pepper Relish is only five ingredients, it’s simple to prepare, it’s so amazingly full of flavor, it makes a perfect sandwich topper, it is one of the best things ever mixed in with hummus, and it is lovely used as a salad dressing; you will want to keep a batch made up in your refrigerator to go with anything else you can dream up! I do!

The most difficult thing about the spaghetti squash is cutting into it! And that’s not hard either. I cut the squash in half, lengthwise. Then I drizzled in some olive oil and added salt and pepper. The squash halves were then roasted, cut-side down on a baking sheet lined with parchment paper for about an hour.  A two-pound squash yielded about 8 cups; this is great reheated, so don’t let that volume scare you.

Once roasted, I removed the seeds and then used a fork to scoop out the long, spaghetti-like strands of squash. With a bit of Roasted Red Pepper Relish on top (a little bit goes a long way), and the addition of toasted walnuts and fresh-cut basil leaves, this dish was simply outstanding.

You really, really need to try it!
