Super Deluxe Steak Nachos

Prepare the steak: Season both sides of steak with salt and peppers. Heat oil in a skillet over medium-high heat. Cook steak, turning occasionally, to medium doneness, about 6 minutes per side. An instant-read thermometer inserted into the center should read 135 to 140 degrees F (60 degrees C). Transfer meat to a bowl to let it rest.

Pour a splash of water into the skillet; stir to scrape up browned bits and deglaze the pan. Pour this liquid over meat. Allow meat to cool completely.

When meat is completely cool, slice thickly (about 1/2 inch) with the grain, then cut into thinner strips. Dice by cutting into pieces against the grain. Transfer chopped steak back to the bowl; toss with the pan drippings.

Make the beans: Melt bacon fat over medium heat in a pot. Add onion and a pinch of salt; cook and stir until softened, 5 to 6 minutes. Stir in oregano. Add pinto beans and water. Bring back to a simmer and cook until onions are soft, about 5 more minutes. Reduce heat to low.

Mash beans with a potato masher to your desired consistency. Add additional liquid if necessary to achieve your preferred texture. Add the remaining salt to taste. Remove from heat.

Preheat the oven to 450 degrees F (230 degrees C).

Assemble nachos: Place tortilla chips about 2 or 3 deep in a heat-proof pan. (You may need more than one pan.) Top chips with spoonfuls of beans and a generous handful of steak pieces. Sprinkle with grated cheese.

Bake in the preheated oven until cheese is melted and edges start to brown, about 10 minutes.

Scatter tomato, avocado, onion, and jalapeño over the top. Drizzle nachos with sour cream and garnish with chopped cilantro.
