Sopa serrana (Andean soup), from Provecho Peru
On her blog about Peruvian cooking and culture, Gretchen of Provecho Peru tells us that her husband eats sopa serrana for breakfast every day, and that occasionally she does, too. Looking at the list of ingredients -- flank steak, squash, fava beans, wheatberries -- I can see why. What a hearty bowl of goodness! Yerba buena might be hard to find in your local market, but I think you can substitute fresh mint leaves.
