1. Prep ingredients
Preheat the oven to 220C, fan-forced. Cut the onion and unpeeled apple into wedges. Crumble 1 stock cube* into a heatproof jug, add 80ml (⅓ cup) boiling water and stir to dissolve.
2. Cook tray bake
Put the onion, apple and sausages in a roasting pan and season with salt and pepper. Pour over the stock, then bake for 25 mins or until the sausages are cooked through.
3. Prep topping
Meanwhile, discard the tough inner stems from the kale, then coarsely chop the leaves. Cut the wholemeal rolls into 2cm chunks. Crush or finely chop the garlic. Put the kale, bread, garlic and 1 tbs olive oil in a bowl, season with salt and pepper and toss to combine.
4. Bake topping
Scatter the bread mixture over the tray bake and bake for a further 5-6 mins until the bread is golden.
5. Serve up
Divide the tray bake among plates or pop the pan on the table for everyone to help themselves. Enjoy!
