Place onion on a baking paper lined tray and spray with oil. Cook in a preheated oven at 200°C for 18-20 minutes or until golden and caramelised. Meanwhile, cut baguette into 12 slices and grill until golden.
Spread Providore Series Pesto on baguette slices and top with capsicum strips, red onion and fetta.
Drizzle with olive oil and sprinkle with pepper. Garnish with basil leaves before serving.
To save time, grilled capsicum strips can be purchased from all leading supermarkets and delis.
