I am having so much fun conceptualizing Lucy Marmalade's en suite cooking next year. Some people define creativity as problem-solving. I agree, which is why frugality also is a creative activity.
Like many people, I have a Robot Coupe processor gathering dust. I use it now and then, but it is a pain and I hate to clean it. My most-used appliance is an el cheapo immersion or stick blender. I love it! Even if you are not in a dorm, you should get one. i love making soup, but always hated pureeing in a blender: it was messy even if all went well. If all didn't go well, you would have pureed carrot soup all over your kitchen and a few burns to boot.
With the immersion blender, you just stick it in the soup pot and push the button. It is also excellent for smoothies (warning: you need a tall container for this. I use something meant to hold utensils on a counter).
To clean your immersion blender, just rinse it off. Seldom do I really need to wash it.
Now I don't know how much soup Lucy M. will be cooking. But the blenders are so cheap that it doesn't matter. I scoff at suggestions to buy a Cuisinart version or a Braun. I'm still using one I got at Walmart for $11.00 many years ago.
I just looked on Amazon and here is the cheapie I will get Lucy. From the comments, I learned that this was recommended by Cook's Illustrated magazine:
