I am also fickle with my food, and a vegan to boot. I solved this problem of leftovers for my situation by making soup. With leftovers, like your tomato sauce, you can always make a soup. Making soup is easy. You can do that in parallel with making dinner, or quickly before breakfast or lunch. You can store and carry it in a thermos flask, or in a simple jar and heat it in a microwave at work. You can also use it as a starter for tomorrow's dinner. Or freeze it for later consumption. Soup, it's great!
