Preheat oven to 350 degrees.
For mini-Peppers, slice one side off and remove seeds. Blanch in large pot of salted boiling water for 4-5 minutes until just slightly softened. Remove from water and drain on paper towels.
Add quinoa, onion, and carrot to 2 cups boiling water. Stir and reduce heat to low and cover. Cook 15 – 20 minutes, stirring at 5 minute intervals until liquid is absorbed and quinoa is tender. Add additional liquid ¼ cup at a time if necessary.
In a large skillet, heat olive oil and brown meat. Add garlic, scallions, and seasoning and cook for an additional minute. Stir in chilies, corn and diced tomatoes and bring to a boil, stirring to incorporate. Remove mixture from heat and stir in cooked quinoa, 1 cup shredded cheese, and fresh cilantro. Adjust seasoning. Then fill peppers with mixture and arrange in a shallow baking dish. Sprinkle with shredded cheese and bake for about 30 minutes.
Serve with sour cream and fresh cilantro leaves.
