'I will write strongly-worded letters if they’re discontinued' – these leak-proof $3 BPA-free food storage gems are a meal prep game-changer

With summer in full swing, I have now started to meal prep salads for delicious lunches during the week.

However, I don't have the right-sized boxes for the job, which is why the Rubbermaid food containers from Amazon are hot to go in my cart. In a twelve-pack, it works out at just over $3 each, which is a great price for quality food storage free from BPA (toxic microplastics).

I have been looking for sturdy kitchen storage ideas to keep my salads fresh and delicious, and there are more than 120,000 Amazon shoppers who agree, rating these an average of 4.7 out of 5 stars.

These Rubbermaid food containers are perfect for meal prep

All prices were correct at the time of publication.

I wasn't sure how to organize the refrigerator to fit my new-found love for meal prepping, but the Rubbermaid food containers from Amazon are just the right size and they're stackable. I'm grabbing a few, so I can fill mine with delicious summer salads and other batch-cooked meals.

Meals are much more time-efficient to make when done in big batches.

But what exactly sets these apart from other food containers you can get? The first thing that I noticed was the fact that they're made from sturdy BPA-free plastic, which means they can be transferred from the freezer and then can be used in the microwave.

The clear plastic also makes it easy to see what's inside them. If you're prepping multiple meals like I plan to, this is perfect, as you won't end up accidentally taking dinner out with you. If you are planning on making any hot food, they have built-in vents for splatter-free microwaving. It'll reduce the need to clean your microwave.

The sturdy locks on them will ensure that salad dressings and sauces won't spill out, which is especially great as I plan to take them on the go for summer picnics. Meanwhile, the air-tight latches will keep the food secure and fresh.

All the brilliant features had already sold me, but the glowing comments from Amazon shoppers really sealed the deal. Over 100,000 reviewers gave them five-star reviews. They say they're well-designed, easy to clean, and last a long time.

Verified shopper Lissa said, 'These are amazing containers. Nothing can stain them. They stack neatly in the cabinet (lids stack best in their own column) and take up very little space. You can throw soup in them in a backpack – they will not leak. Perfectly airtight. They’re very lightweight.

'The clips on the sides can be left open to expose little vent holes while food is cooling. This size is perfect for one adult lunch. We meal prep with them very happily. The price isn’t the cheapest ever, but they are light years better than any other brand or style of Tupperware I’ve ever had in my life. I will buy these every time and write strongly-worded letters if they’re discontinued.'

Swapping your black plastic utensils is another great way to make your home less toxic.
