Heat a large pan to medium-high heat. Add the olive oil, red bell pepper, mushrooms, and red onion.
Saute the veggies for about 5 minutes. Then add the ground meat to the same pan.
While the meat is browning, add the garlic powder, Italian seasoning, salt, pepper, and red pepper flakes (optional). Saute for about 10 minutes or until the meat is cooked through.
When the meat is cooked through, add a jar of your favorite pasta sauce to the pan. Let this simmer for another 5 minutes to heat the sauce.
While the sauce is warming, cook your pasta according to the package. This can be veggie noodles, gluten-free pasta, or any "noodles" of your choosing.
Combine the noodles with the veggie packed meat sauce. Serve and enjoy!
