01 - Combine lentils with 3 cups of water in a saucepan. Bring to a boil, reduce heat, and simmer uncovered for 20 minutes or until tender but not mushy. Drain any excess water.
02 - In a separate pot, add rinsed rice and 2 cups of water with 1/2 teaspoon salt. Bring to a boil, reduce heat, cover, and simmer for 15 minutes or until water is absorbed. Fluff gently with a fork.
03 - Preheat oven to 400°F. Arrange sliced tomatoes on a baking tray, drizzle with olive oil, and season with remaining salt and pepper. Roast for 20 minutes until softened and slightly caramelized.
04 - Fold cooked lentils and rice together in a large bowl. Stir in shredded cheddar cheese while the mixture is still warm, allowing the cheese to melt evenly.
05 - Arrange roasted tomatoes on top of the lentil, rice and cheese mixture. Serve immediately while hot.
