So I had to learn to make them. Bon Appetit magazine to the rescue!
Huevos Rancheros in Tortilla Cups4 tablespoons olive oil, divided
6 6- to 61/2-inch-diameter tortillas
1 15-ounce can pinto beans or black beans, drained
2/3 cup chopped fresh cilantro, divided
1 teaspoon ground cumin
6 large eggs
3/4 cup grated Monterey Jack cheese
1 cup purchased pico de gallo
2 to 3 teaspoons bottled chipotle hot sauce
Preheat oven to 350°F. Brush six 10-ounce custard cups with 1 tablespoon oil. Stack tortillas; microwave uncovered until warm and flexible, about 25 seconds. Gently press 1 tortilla into each cup. Brush tortillas with 2 tablespoons oil.
Place pinto beans, remaining 1 tablespoon oil, 1/3 cup chopped cilantro, and cumin in small bowl; mash coarsely with fork. Spoon bean mixture into bottom of tortilla cups, spreading and dividing evenly. Crack 1 egg into each tortilla cup atop beans. Sprinkle each with grated Monterey Jack cheese, covering egg completely. Bake uncovered until egg yolks are firm to touch and whites are set, about 27 minutes (yolks will still be soft inside).
Meanwhile, mix pico de gallo, 1/3 cup cilantro, and hot sauce in small bowl. Using large spoon, lift tortilla cups from dishes; transfer to plates. Top eggs with pico de gallo and serve immediately.
