Breakfast Tortas

Cut the top third off each roll; hollow out bottom, leaving a 1/2-in. shell (discard removed bread or save for another use). Place roll bottoms on an ungreased baking sheet., In a small bowl, combine the beans, sour cream, cilantro, lime juice, chipotle pepper sauce and salt. Spread 1/4 cup inside each roll. Break an egg into each roll. Bake at 400° for 10 minutes., Sprinkle cheese over eggs. Brush roll tops with olive oil; place on the baking sheet. Bake until egg whites are completely set and yolks begin to thicken but are not firm, 5-8 minutes longer. Top each with bacon, avocado, salsa and onions. Replace roll tops.
