In a large skillet, heat a small amount of non-stick cooking spray over medium heat. Add the chopped onion and minced garlic, sautéing until the onion is translucent.
Add the lean ground turkey or chicken to the skillet, cooking until browned and fully cooked, breaking it up with a wooden spoon. Drain any excess fat.
Stir in the black beans, diced tomatoes with green chilies, frozen corn, and taco seasoning. Mix thoroughly and let it simmer for about 5 minutes. Season with salt and pepper to taste.
In a 9x13 inch baking dish, spread the meat and bean mixture evenly on the bottom.
Sprinkle the reduced-fat cheddar cheese over the top of the mixture.
Bake in the preheated oven for 20-25 minutes until the cheese is melted and bubbly.
Remove from the oven and let it cool for a few minutes. Top each serving with a dollop of fat-free Greek yogurt, sliced green onions, and chopped cilantro for garnish.
Notes
Top with Greek yogurt and fresh herbs for added flavor.
