This easy vegan pasta bake is great because it's so versatile. I've added chopped spinach, pesto and tomato sauce to the plain cooked noodles. But there are lots of options. Try mushrooms or broccoli. A vegan white sauce or a vegan cheese sauce would be a yummy substitute for the tomato sauce. Stir in some hummus, some fresh tomatoes, or even some cooked lentils or chickpeas. Pasta goes well with just about everything!
