Preheat oven to 200C (180C fan forced) and line baking tray with baking paper.
Place pumpkin, zucchini, onion, garlic, 2 tablespoons olive oil and vinegar together in a large roasting pan, tossing until well coated in oil. Season well with salt and pepper. Place pan in preheated oven and roast for 30 minutes, turning halfway through.
For the couscous, heat 1 tablespoon olive oil in a large saucepan over a medium heat. Add pearl couscous and cook for 3-4 minutes or until golden. Pour over vegetable stock, reduce heat to low, cover and cook for 16 minutes or until stock has been absorbed. Stir occasionally.
For the kangaroo, heat remaining oil in large non-stick frying pan over a medium-high heat. Rub kangaroo with dukkah, place in frying pan and brown the meat on all sides. Transfer kangaroo to prepared baking tray and cook in preheated oven for 5 – 10 minutes, depending on its thickness. Remove from oven and rest for 10 minutes before slicing thinly.
To serve, combine roasted vegetables, couscous, sliced kangaroo, mint, coriander and lemon juice together in a large mixing bowl, tossing until well combined. To finish, sprinkle over feta and almonds.
