Roast the veggies – Preheat oven to 400°F. On a baking sheet, toss butternut squash, onion, and garlic with olive oil, salt, and pepper. Roast for about 20 minutes, until squash is tender.
Blend the sauce – In a blender, combine roasted vegetables, parmesan (or nutritional yeast), sage, and 1 cup vegetable broth. Blend until smooth, adding more broth to reach a creamy, pourable sauce. Adjust salt and pepper to taste.
Assemble bowls – Divide sauce between 3 containers. Top each with cooked pasta, broccoli, and lemon pepper tofu.
Store & serve – Store in the fridge for up to 5 days. To serve, stir everything together and heat, adding a splash of broth or water if needed. Enjoy hot or cold!
