Mushrooms are something of a favourite here at the Wellbeing Studios. Not only are they totally delicious, but they’re teeming with wellbeing wins, too.

Research shows that those who eat mushrooms may be less likely to struggle with depression. Plus, they’re a valuable plant-based source of vitamin D. Mushrooms, just like human skin, produce this vital vitamin when the sun shines on them. Placing your mushrooms on a windowsill to ripen for an hour will add significantly to their vitamin D content.

And, while it may not be the first food that springs to mind when we think of wellbeing, halloumi has a number of health benefits, too. Rich in protein, it can help us to feel full for longer, meaning we’re far less likely to snack on sugary treats.

Serve our tempting mushroom and halloumi burger recipe with tomato, plenty of rocket and a fresh bun. They taste especially delicious when paired with a glass of kombucha too!
