If you don't get bored too easily, you could do something different for each week, but make a week's batch at once, on Sunday evening, and eat it through the week.
For soups, you've got your basic vegetable soup, to which you can add a bit of barley or rice (avoid noodles - they'll soak up all the liquid) or pureed vegetable soups (broccoli, carrot, asparagus, squash etc). Or make some yoghurt based dip or hummus, and cut up some vegetables into a container, and have a handful of veggies and a bit of dip. One of my favourite yoghurt based dips is yoghurt + Indian lime pickle, which is wonderfully flavourful. I like roasted chickpeas as well.
Granola could be a good option, if you're careful about portion size - it's pretty healthy, but can be calorically dense. One of my favourite mixes is 4 parts oats to 1 part millet, 1 part shelled pumpkin seeds, 1 part flaked almonds. Then I mix that with molasses, a bit of oil, slivered orange zest, cinnamon, cloves, ginger and vanilla (enough liquid to moisten, and warm in the microwave before adding it to the dry ingredients).
