Multi-coloured baby capsicum (the supermarket had them in a pack), halved and briefly sautéed in a pan
Halved cherry tomatoes (the purple ones)
Red onion thinly sliced (which I forgot to add!)
Pistachio nuts (added after the photo)
Dressing of balsamic vinegar, olive oil, lemon juice and garlic
Simple. Colourful. Tasty.
