Why do we need leftover veg recipes? It’s simple, they’re designed to help you make the right food choices for your health and the environment.

I’ve felt the guilt of tossing food many times, and it has nudged me to break new ground with leftovers.
Why throw away veggies if they can be made into something healthy and delicious?

What are leftover vegetables?

By ‘leftovers’ we mean food that’s left after the rest has been used. So leftover veg is any unconsumed veggies that you can save for later.

Benefits of eting leftover vegetables

The main benefit of eating leftover veggies is devoted to battling food waste.

Even though this type of waste is biodegradable, it doesn’t cancel the waste of resources, such as land, water and labor. Produce doesn’t magically appear on our tables, right?

Let’s not forget about the pleasant bonus for your health and wallet. With a thought-out meal plan, you won’t have to spend extra time and money on groceries.

Preparing your leftovers

Leftover ingredients can enhance many meals, especially fritters, stir-fries, soups and casseroles. So how you deal with leftovers will depend on a particular recipe.

Here is some general advice on how to turn your leftover veggies into a delicious meal.

Safety tips

Always prioritize food safety as it directly impacts your well-being!

• Refrigerate leftovers as soon as they’ve cooled down (within two hours).
• Use leftover cooked vegetables within 3-4 days. If I have a lot going on in my fridge, I usually mark my containers with the date.
• Keep cooked leftovers away from raw foods to avoid cross-contamination.

Choosing the right produce

It’s important to consider that some ingredients work better as leftovers than others.

• Make a smart shopping list with fresh and high-quality foods. Fresh vegetables are an excellent way to dive into healthy leftover food recipes.
• Go for sturdier vegetables like potatoes, carrots, bell peppers etc. I particularly like root vegetables for their firm texture.

Storage tips

Provide proper storage conditions for your leftover vegetables.

• Transfer cooled leftovers to airtight containers and store them in a refrigerator set below 40°F (5°C).
• Don’t overfill your fridge because it can mess up with air circulation and temperature.
• If you have leftover veggies you can’t use within 3-4 days, consider freezing them.
