Preheat oven to 230°C. Line a large baking tray with baking paper. Cut vegetables into 2cm pieces and place a bowl. Pour in the oil and stir to distribute well then place in a single layer on the tray. Season with salt and pepper. Roast vegetables, turning once, for ~20 minutes or until golden and tender. Set aside to cool to room temperature. Heat a non stick frying pan over medium heat. Add pine nuts and cook stirring for about 3 minutes or until golden. (Take care not to burn them) Combine honey, vinegar and oil in a screw top jar. Secure lid and shake to combine. Remove lid. Microwave on high for 10 seconds or until honey is melted. Replace lid and shake until well combined. Place vegetables over spinach in a large bowl (or on two smaller serving platters). Sprinkle with pine nuts and crumbled feta. Drizzle with dressing and serve.
