Meets Patient’s editorial guidelines

This vibrant chicken burger recipe offers a lighter, high-protein alternative to the traditional takeaway classic. By ditching the heavy bun in favour of a single slice of toasted country bread, the focus shifts to the quality of the ingredients and the bright, herbal notes of the homemade basil mayonnaise. The addition of tangy cornichons and fresh heirloom tomatoes provides a refreshing crunch that perfectly complements the succulent, seasoned chicken mince.

Ideal for a sophisticated weekend lunch or a quick mid-week dinner, these open-faced burgers are as visually appealing as they are nutritious. The basil-infused mayonnaise doubles as both a binder for the meat and a zesty topping, ensuring every bite is packed with flavour. Serve them alongside a crisp green salad for a balanced, modern meal that feels indulgent without being heavy.
