Grilled Chicken and Ratatouille

This grilled chicken and ratatouille is a vibrant, Mediterranean-inspired dish that celebrates the natural flavours of sun-ripened vegetables. By charring the courgettes, aubergine and peppers on the grill, you achieve a wonderful smokiness that perfectly complements the succulent, herb-infused chicken. It is a light yet deeply satisfying meal that feels special enough for a weekend lunch but remains simple enough for a quick weeknight dinner.

As a diabetes-friendly option, this recipe focuses on lean protein and high-fibre vegetables, making it a nutritious choice for those monitoring their blood sugar levels. The combination of fresh basil and a touch of red wine vinegar provides a bright finish without the need for heavy sauces. Serve it exactly as it is for a low-carb feast, or with a small portion of quinoa or brown rice for a complete, wholesome dinner.

How to make Grilled Chicken and Ratatouille
