Heat a large pot or sauté pan to high heat, then add coconut milk, water, Italian seasoning, nutritional yeast, and salt and stir to combine.
Add pasta, carrot, zucchini, squash, bell pepper, and shallot.
Bring to a boil, reduce to medium heat, and cook for 5-8 minutes, stirring occasionally, until the pasta is nearly al dente.
Add broccoli, peas, and tomatoes, and cook for another 3-5 minutes.
Once the pasta is cooked to your liking, remove from heat and stir in lemon juice.
Season with salt and pepper to taste and let it sit for a few minutes.
After the pasta has thickened it is ready to serve.
