Prepare lentils:

• Rinse the lentils under cold water and remove any debris.
• In a saucepan, add the lentils and cover them with water. Bring to a boil, then reduce the heat and simmer for about 20-25 minutes until the lentils are tender but not mushy. Drain and set aside.

Cook the rice and pasta:

• In separate pots, cook the rice and macaroni according to their package instructions. Once cooked, fluff the rice with a fork and drain the macaroni. Set both aside.

Prepare the tomato sauce:

• In a large skillet, heat the vegetable oil over medium heat. Add the sliced onions and sauté until they turn golden brown and caramelized.
• Add the minced garlic and sauté for another minute until fragrant.
• Stir in the chopped tomatoes, tomato paste, cumin, ground coriander, cayenne pepper, salt, and black pepper. Simmer the sauce for about 10-15 minutes, allowing the flavors to meld.

Assemble Kushari:

• Mix the cooked rice, macaroni, and lentils together in a large serving dish.
• Drizzle the white vinegar over the mixture and gently toss to combine.

Serve:

• To serve, plate a generous portion of the rice, macaroni, and lentil mixture. Top it with a ladle of the spiced tomato sauce.
• Garnish with optional toppings like crispy onions, cress and chickpeas for added flavour and texture.
