I love milanesas. They're not very healthy and they're a bit of a pain to make (or rather, to clean up after), but they are soooo good.
Last night I made them with some very thin meat from Safeway I didn't even need to beat up. The empanadas were extremely tender and wonderful in thin slices of sourdough bread with lemon juice, tomato slices and baby spinach. Yummmm.
