A Mexican street-food mainstay, tortas are generously stuffed sandwiches that come in many variations, with one thing in common: They’re bursting with meat and veggies. Ours spills over with thin slices of breaded steak—inspired by Milanese veal cutlets—and frijoles, a black bean paste that’s commonly used in many dishes, not to mention juicy tomatoes, diced avocado and smokey chipotle sauce. You can also serve up tortas in the morning—breakfast burrito who?
