Method

In large saucepan or Dutch oven, heat oil over medium heat; cook onions, garlic, ginger and curry paste, stirring occasionally, for 5 minutes or until softened.

Add tomatoes, breaking up with spoon. Add vegetable stock, water and lentils; bring to boil. Reduce heat to medium-low; simmer for about 20 minutes or until lentils are softened.

Add chickpeas, red kidney beans and black beans; cook for 15 minutes or until heated through. (Make-ahead: Let cool for 30 minutes; refrigerate in shallow airtight containers for up to 2 days or freeze for up to 2 weeks. Reheat to continue.)

Stir in coriander, lemon juice, salt and pepper.
