you can wash out and reuse the little plastic tub containers that things like yogurt and cottage cheese come in
and if you like, you can remove the ink labeling with a cloth or paper towel, 100% acetone nail polish remover, and a little bit of elbow grease
I'm really excited about getting free containers

Really good idea, but I'll have to be a hair in the soup. On an environmental panel discussion a polymer researcher (someone deeply opposed to single use plastic btw) made the point to be extremely careful when using plastics outside its intended use case around food. Temperature, acidity and lipids (fat) can break down plastics not designed to withstand them. So microwaving your fried lemons in a random plastic container is something I would be hesitant to do. Not saying you'll die, but please be careful!
