I hate waste, and I hate being disorganized. It wastes too much of my time trying to find the things I need to make a meal. I often purchase lettuce and other items that are sold in those clear, plastic containers.
I have discovered that these make great bins for organizing my refrigerator, freezer and cupboards. I can use the lids if I want, or just use them for open containers. I fill them with containers of yogurt and overflow veggies and fruits in my frig. I use them to store meat, rolls and breads, nuts and cheeses, etc., in my freezer. They are clear, so I can see the contents, and I they come in various sizes, so I can fit them easily in a variety of spaces.
Have fun organizing!
