Stay away from plastic containers, especially single-use ones. They are full of chemicals, they are terrible for the environment and after one use you throw them out. You might as well be throwing away wads of cash. Use these glass containers instead. They don't cause cancer (BPA-free), they are easy to stack (keeps your fridge organized) and air-tight (they seal in your food's freshness). These are perfect for weekly menu planning and meal prep.
