1. Cook quinoa: In a saucepan, bring quinoa and water to a boil. Reduce heat to low, cover, and simmer for 15 minutes or until water is absorbed. Fluff with a fork and let cool.
2. Prepare veggies: While quinoa is cooking, chop the red bell pepper, cucumber, and grate the carrot.
3. Mix ingredients: In a large mixing bowl, combine the cooked quinoa, chopped veggies, cilantro, lemon juice, olive oil, salt, and black pepper. Mix well.
4. Assemble wraps: Lay out the tortillas and spoon the quinoa mixture onto each one. Roll up tightly and serve.
