In this recipe from the September 2018 issue of Rachael Ray Every Day Magazine, Rach serves up nachos with the chips on the side and the toppings piping hot and ready for scooping.
Preheat the oven to 400°.
Heat a medium cast-iron skillet over medium to medium-high. Add the oil, two turns of the pan. Add the beef. Cook, stirring occasionally and breaking up the meat with a spoon, until browned, about 5 minutes; season with salt and pepper. Add the spices. Cook, stirring often, until aromatic, about 1 minute. Add the onion, chile, and garlic. Cook, stirring often, until softened, about 3 minutes. Add 1/2 cup water. Cook, stirring often, until absorbed, about 4 minutes. Stir in the beans. Reduce heat to low.
Scatter the chips on a rimmed baking sheet. Toast in the oven until lightly browned, 3 to 5 minutes. Transfer to a basket or bowl. Switch on the broiler.
Top the beef and beans with the cheeses. Broil until browned and bubbly, about 2 minutes. Top with the tomato, oregano, jalapeño slices, cilantro, avocado, and scallions.
Serve the dip directly from the skillet with the chips.
