Filet Carne Asada With Guacamole and Refried Beans

For the refried beans: Put beans, onions, and water in a medium pot and bring to a boil over high heat. Reduce heat to medium-low and simmer until beans are very tender, 1-2 hours. Discard onions. Drain beans, reserving cooking liquid.

Heat lard in a medium skillet over medium heat. Add 1/4 of the beans and mash to a paste with a fork or potato masher. Repeat process, adding remaining beans and some of the reserved cooking liquid as needed for a smoother, looser consistency. Season to taste with salt. Cover and keep warm over low heat. (Stir in a little more of the reserved cooking liquid if beans dry out.)

For the tortilla chips: Pour oil into a small skillet to a depth of 1 inch and heat over medium heat until hot. Fry tortillas until golden, about 30 seconds per side. Drain on paper towels and sprinkle with salt.

For the guacamole: Halve avocados lengthwise and remove and discard pits. Scoop out pulp, puree in a food processor, then transfer to a bowl. Stir in onions, tomatoes, and cilantro, and season to taste with salt. Cover surface with plastic wrap and set aside.

For the rajas: Preheat broiler. Broil chile in a pan until skin is charred, about 5 minutes per side. Transfer to a bowl and cover. When cool, peel and seed chile, then slice lengthwise into thin strips and set aside.

For the meat: Preheat grill. Lay filets flat on a cutting board. Using a thin, sharp slicing knife, make a 1/2-inch cut the length of each fillet; begin slicing meat, "unrolling" it into one long 1/2-inch-thick strip. Keep knife parallel to cutting board and meat and maintain a 1/2-inch thickness as you slice. Cut each strip in half crosswise. Squeeze lime juice over meat, then season liberally with salt and pepper. Grill over a medium-hot fire, 3 minutes per side for medium rare.

Divide meat among individual plates and garnish each with rajas. Spoon some refried beans and some guacamole onto each plate alongside meat, sprinkle beans with queso fresco, then stick a tortilla chip into beans.
