Bring a large pot of salted water to a boil. Cook pasta until al dente. Reserve 2 cups of pasta water before draining.
Heat a large pan over medium-high heat. Add olive oil, chili flakes, and onion. Sauté for several minutes until onion starts to soften. Add in garlic and frozen peas. Toss to combine.
Add in sauce, ¾ of the smoky mushrooms, spinach, and cooked pasta. Toss to coat and heat through.
Use the pasta water to thin out to desired consistency. Add on vegan parmesan, salt, and cracked pepper, and coconut bacon, and serve immediately.
