Heat some avocado oil in a large skillet or pan over medium heat. Add the diced onion, orange pepper, and sliced mushrooms. Sauté until the onions are almost translucent and the vegetables are slightly softened.
Add the broccoli florets without the stems to the skillet and continue stirring until the onions are fully translucent.
Season the vegetables with salt and pour in 1.5 jars of pasta sauce. Stir everything together and bring the sauce to a simmer.
Add the spinach to the skillet and stir until it wilts. Cover the skillet with a lid and let it simmer for a few minutes to allow the flavors to meld together.
Reduce the heat to low and let the sauce simmer for an additional 10 minutes. If using Lucky Iron Leaf or fish, carefully add to the sauce and let it simmer for 10 minutes and then remove.
Meanwhile, cook the pasta according to the package instructions until al dente.
If desired, add a little pasta water to the sauce to adjust the consistency and enhance the flavors.
Drain the cooked pasta and add it to the skillet with the sauce. Stir everything together to ensure the pasta is well-coated.
Serve the pasta and sauce mixture in bowls or plates. Enjoy your flavorful and nutritious pasta dish!
