The easiest vegan meal to make is pasta. EVERYTHING goes with pasta. Just pick your favorite vegetables and hop to it!
I made this pasta salad to take to work for lunch. Here I started with Ancient Harvest Gluten Free Organic Pasta (made with quinoa), and added steamed zucchini and yellow squash, grape tomatoes, black olives, sundried tomatoes, Italian dressing (Whole Foods 365 brand) and vegan grated topping from Galaxy Nutritional Foods. I usually only make two days' worth at a time because I'm a little picky about "leftovers." But you can probably make up to 4 days' worth and it would still be good.
