Roast Vegetable Reinvention

Leftover Roast Vegetable Stir-Fry with Mushrooms, Tomato, and Turmeric

Give your roast vegetables a delicious second life with this vibrant and nutrient-packed recipe. Leftover roast vegetables are diced into bite-sized chunks, then sautéed with brown onion and minced garlic for a rich and aromatic base. Tender button mushrooms add an earthy depth, while fresh tomato brings brightness and juiciness to the mix.

Seasoned with low-salt soy sauce for umami, a sprinkle of nutritional yeast for a cheesy, savoury flavour (and a boost of B vitamins), and enhanced with freshly grated ginger and turmeric. A dash of grated black pepper helps release and activate curcumin—the potent anti-inflammatory compound in turmeric—turning this into more than just a meal; it’s nourishing medicine on a plate.

Health Benefits:

  • Turmeric & Black Pepper: Turmeric contains curcumin, which has potent anti-inflammatory and antioxidant properties. Black pepper enhances curcumin absorption, boosting its benefits for joint health and immune support.
  • Garlic & Onion: Both are rich in sulfur compounds that support heart health, boost immunity, and may reduce inflammation.
  • Mushrooms: Packed with immune-supporting antioxidants and vitamin D, mushrooms contribute to stronger immunity and overall well-being.
  • Tomatoes: A great source of lycopene, an antioxidant that may protect heart health and support skin’s natural defence against sun damage.
  • Nutritional Yeast: High in B vitamins, particularly B12 (if fortified), which supports energy production and brain health in plant-based diets.
  • Ginger: Known for its digestive benefits and ability to help reduce nausea and inflammation.

This dish is not only a delicious way to prevent food waste, but it’s also a powerhouse of antioxidants, vitamins, and anti-inflammatory compounds. Perfect as a light lunch, a quick dinner, or a vibrant side dish, it proves that leftovers can be both flavorful and incredibly healthy.

Normally you might find me behind the coding of our sites but over the years I have become much more concerned about what has been happening in the kitchen as well - families do that for all of us don't they? Background experience is in Account Management and Web Development but as my passion has grown for WFPB so has my desire to speak out.
