Rinse the quinoa under cold water. In a medium saucepan, combine the quinoa and vegetable broth. Bring to a boil, then reduce heat to low, cover, and simmer for about 15 minutes or until the quinoa is fluffy and the liquid is absorbed. Remove from heat and let it stand for 5 minutes, then fluff with a fork.
In a large skillet, heat a splash of oil over medium heat. Add the diced red bell pepper and sauté for 3-4 minutes until slightly tender.
Add the black beans, corn, cumin, chili powder, salt, and pepper to the skillet. Stir well and cook for an additional 5-7 minutes until everything is heated through.
In a mixing bowl, combine the cooked quinoa, sautéed mixture, and cherry tomatoes. Adjust seasoning if needed.
To assemble the wraps, lay one large wrap or tortilla flat. Add a generous portion of the quinoa mixture and some diced avocado.
Fold in the sides of the wrap and roll it up tightly from the bottom to the top. Repeat with the remaining wraps.
Serve the wraps with fresh cilantro and lime wedges on the side for added flavor.
