I've lightened up these easy nachos by using baked tortilla chips, reduced fat cheese, nonfat Greek yogurt (in place of sour cream), and a ton of fresh veggies. This recipe is super versatile and maybe you prefer to use black beans or to add chicken, ground beef, extra cheese, or different veggies. I say go for it!
Preheat oven to 400 degrees F. Coat a large baking sheet with cooking spray or line with foil. Spread tortilla chips on the baking sheet in an even layer. Sprinkle with cheese and top with beans. Bake 5-6 minutes, turning pan halfway to ensure even cooking.
While nachos are cooking, mix Greek yogurt with taco seasoning in a small bowl and set aside. Make sure all your other ingredients are prepped and ready for adding to your nachos.
Remove nachos from the oven and sprinkle evenly with fresh tomatoes, scallions, black olives, avocado, and hot peppers if desired. Dollop with Greek yogurt mixture. Serve immediately with margaritas!
