Step‑by‑Step Instructions

1. Gather your scraps: While prepping the vegetables, set aside onion skins, carrot tops, celery leaves, and herb stems in a small bowl. These will form the base of a quick broth.
2. Make a 2‑cup broth: In a saucepan, combine the saved scraps with 2 cups water, a pinch of salt, and a splash of olive oil. Bring to a gentle simmer for 5 minutes, then strain. (You can also store the unstrained broth for extra texture.)
3. Sauté aromatics: In a large, deep skillet or Dutch oven, heat 2 Tbsp olive oil over medium heat. Add the diced onion, carrots, and celery. Cook, stirring occasionally, until softened, about 3 minutes.
4. Add garlic & herbs: Stir in minced garlic, dried oregano, and red‑pepper flakes. Cook for another 30 seconds until fragrant, being careful not to burn the garlic.
5. Incorporate tomatoes: Pour in the crushed tomatoes and tomato paste. Mix well, allowing the mixture to bubble gently for 2 minutes. This deepens the flavor and creates a rich sauce foundation.
6. Combine broth and pasta: Add the strained vegetable‑scrap broth to the pot, then immediately stir in the dry pasta. Ensure the pasta is mostly submerged; add a splash of extra water if needed.
7. Cook the pasta: Bring the mixture to a boil, then reduce to a simmer. Stir occasionally to prevent sticking. Cook for 10‑12 minutes, or until the pasta is al dente and most of the liquid has been absorbed, creating a creamy coating.
8. Season & finish: Taste and adjust salt and pepper. If you’d like a richer mouthfeel, swirl in a drizzle of olive oil or a tablespoon of nutritional yeast.
9. Stir in optional protein: Add cooked chickpeas, tofu, or shredded chicken now, allowing them to warm through for 2 minutes.
10. Garnish: Sprinkle chopped parsley or basil stems over the top. Serve hot, straight from the pot, for maximum comfort.

• Broth reserve: Any leftover vegetable‑scrap broth can be frozen in ice‑cube trays for quick future use.
