Recipes like the HelloFresh Zesty Citrus Chicken and Ginger Stir Fry, or Cod in a Lemon and Chive Butter help get the best of the acidic flavours, complementing them with spices and herbs that create a delicious meal the whole family can enjoy.


A versatile fruit, the tomato can be easily included in your daily balanced diet in several ways. Whether via a sauce like the HelloFresh King Prawn and Tomato Sauce Fresh Tagliatelle or in the form of cherry tomatoes such as the Cheesy Tomato, Chorizo and Mozzarella Orzo Risotto, these delicious tomato dishes are bound to increase the size of the smile on your face.


Salads are the ideal way to get more fruit and vegetables into your diet, ensuring you can achieve a healthy, balanced diet that may help improve your optimism and increase your happiness levels. 

Specifically, green salad has been linked to changes in mental health. An excellent way to incorporate these into meals is with recipes like the HelloFresh Goat’s Cheese and Fig Salad – the perfect accompaniment to any meal. Or, even make the salad the main with the Waldorf Style Salad with Chicken and Bacon.

Leafy vegetables

Leafy, green vegetables are bursting with vitamins, minerals and fibre that contributes hugely to the healthy, balanced diet that is so importantly linked with theorised improvement on mental well-being.

Incorporate leafy greens like spinach with the HelloFresh Spinach and Ricotta Lasagne, or even the Paneer and Spinach Chicken Curry, for an extra bit of spice.
