Ingredients
  

  • 12 ounces spaghetti or pasta of choice
  • 4 tablespoons olive oil
  • 1 cup chopped onion
  • 2 medium zucchini chopped
  • 2 medium yellow squash chopped
  • 3 garlic cloves minced
  • ½ teaspoon dried oregano
  • ¼ teaspoon red pepper flakes
  • 2 tablespoons tomato paste
  • 1 28 ounce can whole peeled tomatoes
  • 1 12 ounce jar roasted red peppers, drained and cut into pieces
  • 2 to 3 teaspoons mushroom powder optional
  • 5 cups spinach leaves
  • Handful fresh basil leaves
  • Salt
  • Fresh ground black pepper
  • Parmesan cheese or nutritional yeast for serving

Instructions
 

  • Heat olive oil in a wide skillet over medium heat. Add chopped onion and cook until softened, about 3–5 minutes.
  • Add zucchini, yellow squash, garlic, oregano, red pepper flakes, and a pinch of salt. Cook while stirring occasionally for 5–8 minutes until vegetables soften but still have a slight crunch.
  • Stir in the tomato paste and cook for about 1 minute to deepen the flavor.
  • Add roasted red peppers, whole peeled tomatoes, and mushroom powder if using. Bring the mixture to a gentle simmer.
  • Cook the sauce for about 10 minutes until it thickens and reduces. Use a spoon to break up the tomatoes into smaller pieces for a chunky vegetable pasta sauce.
  • Meanwhile, bring a large pot of salted water to a boil and cook spaghetti according to package instructions.
  • Remove the sauce from heat and stir in the spinach and fresh basil.
  • Add the cooked pasta to the skillet and toss everything together. Let it sit for a minute so the pasta absorbs the sauce.
  • Toss again and serve the Easy Veggie Spaghetti topped with parmesan cheese or nutritional yeast.

Notes

For a vegan version, simply use nutritional yeast instead of parmesan cheese.
