Wash and peel* the veggies and cut into large chunks. Add the veggies and fennel to the food processor bowl and blitz until a fine dice.
Heat a large skillet with 1 - 2 tablespoons olive oil over medium heat. Spoon the veggie mixture into the hot skillet, stirring as needed until the veggies are soft, fragrant and translucent - approximately 7-10 minutes. Deglaze with a splash of water, white wine or veggie broth as needed.
Add the oregano, balsamic vinegar and hot pepper flakes stirring to incorporate. Add the tomatoes and a splash of starchy cooking water to loosen the sauce as needed.
Taste the sauce, season with salt and pepper. Stir in ¼ teaspoon baking soda if the sauce is too acidic.
Once you've drained the pasta (don't forget to reserve ~1 cup of cooking water), pour the pasta into the pan of sauce and stir to incorporate. Add enough starchy water to get a silky creamy sauce (splash or two at a time). Taste and adjust seasonings as needed.
Top with grated parmesan cheese, basil ribbons, red pepper flakes, and the Italian herb crusted tofu.
