1.Heat oil in a large frying pan on high. Sauté onion, garlic, cumin and coriander for 1-2 minutes, until onion is tender and mixture is aromatic.
2.Add prawns and asparagus. Cook, stirring for 2-3 minutes until prawns change colour and are cooked through. Add capsicum and toss vinegar, walnuts and syrup through.
3.Place radicchio and half the ricotta in a bowl. Add warm prawn mixture and toss gently. Serve immediately topped with remaining ricotta. Accompany with bread.
If you don’t like the bitter taste of radicchio, use baby cos leaves instead.
