Sausages and lentils with polenta

Method

• Step 1
  Heat a large, non-stick frying pan over medium heat. Lightly spray sausages with oil. Cook sausages, turning often, for 10 to 12 minutes or until cooked through. Transfer to a board. Cut sausages diagonally into 1cm-thick slices. Cover and set aside.
• Step 2
  Spray pan with oil and return to medium heat. Add onion. Cook, stirring often, for 3 to 4 minutes or until tender. Add cumin and turmeric. Cook for 1 minute or until aromatic. Add zucchini and 3/4 cup cold water. Cook, stirring occasionally, for 4 to 5 minutes or until zucchini is just tender. Add lentils and tomatoes. Cook for 2 to 3 minutes or until tomatoes just start to collapse. Return sausages to pan. Cook, stirring occasionally, for 1 to 2 minutes or until heated through. Season with salt and pepper.
• Step 3
  Meanwhile, bring 3 1/2 cups cold water to the boil in a large, heavy-based saucepan over high heat. Add polenta in a thin, steady stream, whisking constantly until combined. Reduce heat to medium-low. Cook, stirring occasionally, for 5 to 6 minutes or until grains are soft. Remove from heat and season with salt and pepper.
• Step 4
  Spoon polenta onto plates. Top with sausage mixture and yoghurt. Serve.
