Add the olive oil to the pot. Once hot, add the chopped onions, carrots, celery, and garlic. Generously salt and pepper. Sauté for 4-6 minutes to soften.

Add the vegetable broth, diced tomatoes, tomato paste, Italian seasoning, and crushed red pepper. Bring to a boil.

Once boiling, stir in the kidney beans, great northern beans, green beans, and pasta. Stir well and simmer for 8-10 minutes, partially covered. Make sure to stir every 2 minutes, so the pasta doesn’t stick to the bottom.

Finally, add in the sliced zucchini, spinach leaves, and parsley. Stir and simmer for 2 minutes. Taste, then salt and pepper as needed. Serve warm.
