Preheat the oven to 400°F.
Line a baking sheet with parchment paper and spread 1/3 of the bag of tortilla chips across the sheet in an even layer. Sprinkle 1/3 of the cheese over top and top the cheese with 1/3 of the shredded chicken. Finally, spoon 1/3 of beans on top of the chicken. Repeat these steps until you run out of tortilla chips, cheese, beans, and chicken.
Transfer the nachos to the oven and bake for 10 minutes or until the cheese has melted and the chips are lightly golden.
While the chips are in the oven, place the onion, tomatoes, jalapeño, avocado, and cilantro in a medium-sized bowl. Add the lime juice, olive oil, cumin and salt. Toss to coat.
Take the chips out of the oven and spoon the tomato mixture over top. Add a dollop of yogurt and serve immediately with beer.
